CHEMICAL SCIENCE AND ENGINEERING AT BERKELEY Newsletter of the College of Chemistry, University of California, Berkeley Volume 9, Number 3, August 2001 College Construction Update Or "How much longer is this drilling going to last?" Yes, the jack-hammering can seem interminable. But Susan Slavick, the Building Manager for the College of Chemistry, assures us that there is an end in sight. And when it is all over, both Hildebrand and Latimer will be upgraded for seismic structure and life safety, with automatic fire sprinklers installed in all the offices and labs.

So far everything is pretty much going according to schedule, and the projects should be completed in the spring of 2002,” Slavick said. The labs on the second and third floor of Hildebrand will then provide surge space for the scientists who will be vacating Stanley as construction for its replacement building begins. In addition to the seismic upgrades and the renovation of several “surge” labs, other large construction projects around the Chemistry Complex are also near- Changing Faces at Latimer Upcoming Events..................8 In Memoriam: Andrew Dorsey....8 Photos by Jane Scheiber The College of Chemistry bade a fond farewell to long-time staff members (above, left to right) Betty Rancatore, who retired as Chemistry Management Service Officer (MSO) after over 26 years at the university; Irene Katsumoto, who retired after 11 years of service, most recently as Assistant to the Dean; and Rebecca Pauling, who transferred to Integrative Biology after 10 years with Chemistry. Betty was presented with the Berkeley Citation. ing completion. “The Marletta labs in Lewis will be ready at the end of August, and the second phase of the Bertozzi labs on the eighth floor of Latimer will be completed in October,” Slavick said. “The faculty and staff members have dealt with all of the noise and hubbub incredibly well,” Slavick added. Dean Heathcock commended Slavick for “an outstanding job in keeping everyone informed so they could plan their schedules to avoid the worst of the noise and vibration.” “The complaints have been minimal and the building occupants have been fantastic—patient and understanding. This will greatly contribute to the final overall success of this very complex and difficult project,” Slavick said. The website http://www.cchem.berkeley.edu/ ~physplnt/Seismic/retrofit.html offers photos and updates of the seismic project as well as a three-week rolling schedule, so you can find out where the noise and dust will be ahead of time. Joel Nice (below left), formerly with the Electronic Research Lab, is the new MSO for Chemistry. He assures us that he is enjoying the many challenges of his job. Rebecca Egger (below, center) is the new senior analyst and Assistant to the Dean. She comes to the College from the University of Michigan, where she was a member of the English Department faculty. This new position, in addition to academic personnel, will involve high-level analysis for the Dean on a broad range of issues. Adam Lieb (below right) is the new Assistant Building Manager. www.cchem.berkeley.edu New Faculty Members Bridge Chemistry and Biology Jamie Cate: Protein Synthesis 101 Assistant Professor Jamie Cate could be a poster boy for the benefits of undergraduate research. “I was interested in chemistry back in high school and majored in it as an undergraduate. But I was getting bored with the classes. The professors stressed rote memorization, and while I was good at it, it wasn’t much fun. Luckily, I started working in a lab with a good professor who really communicated to me that science was an ongoing process that was both exciting and unpredictable.” Cate, who has a joint appointment with Molecular and Cell Biology, still exudes enthusiasm talking about his research. “I’m interested in ribosomes and protein synthesis, one of the most fundamental biological processes,” he explained. “Protein synthesis is conserved in all organisms, from bacteria up through to humans.” Our genetic information is stored in DNA. However, in order for that information to ultimately lead to cells, tissues and people, the DNA is first transcribed into messenger RNA (mRNA), which travels out of the nucleus and is translated by the ribosome into proteins. are not purified with the ribosomes, such as EF’s, elongation factors, and the associated mRNA and tRNA, are purified individually and added back to the system later. “We add back only the pieces of the puzzle that we want to study,” he said. “Decoding is the next process to look at,” Cate said. Decoding is the actual reading of the set of three nucleotides, known as a codon, in the mRNA, that codes for an amino acid. The ribosome protein factory moves along the mRNA three nucleotides at a time, reads that codon, and using the correct tRNA, attaches an amino acid at the right place in the growing protein chain. The ribosome then moves to the next codon and begins again. “It sounds like a simple process but there’s much that we don’t even begin to understand. Like, how does the tRNA get chosen, and how does the ribosome move from one tRNA to the next? We know that the elongation factor EF-Tu and the small molecule GTP are involved in choosing the tRNA. We also know that EF-G and GTP are involved in the ratcheting of tRNA through the ribosome.” “For decades we have studied the ribosome using genetic and “In order to crystallize these complex protein assemblies in very biochemical means, but the structure was not known until recently.” defined states, we use a number of little tricks,” Cate explained.

Cate and his colleagues also identified the positions of tRNA in three of its binding states and observed many of the ribosomal proteins. Further, they could distinguish single strands of the RNA, even in the double-helical regions. “Getting that kind of resolution of such a complex protein factory allows us to ask all sorts of interesting questions now,” Cate remarked. “Like how does the ribosome read the genetic code and choose the correct tRNA? How do certain antibiotics cripple bacterial ribosomes and distinguish between mammalian ribosomes and their bacterial targets?” Bacterial ribosomes have 50–60 parts and can be purified gently so that they emerge intact and functional. The accessory factors that www.cchem.berkeley.edu 2 are collaborating with groups such as Adam Arkin’s. Their computational expertise complements our molecular biology research in understanding these complex systems,” Cate said. A native of Colorado, Cate received his B.S. in chemistry from the University of Denver in 1990. He earned his Ph.D. in 1997 from Yale University, studying the structure of catalytic RNAs with Jennifer Doudna, and was a postdoc with Harry Noller at UC Santa Cruz. After two years as an Associate Member of the Whitehead Institute and Assistant Professor at MIT, Cate has now moved his lab to UC Berkeley. “I do a fair amount of structural studies and Berkeley has great facilities for my experiments, including the ALS (Advanced Light Source at LBNL), which is well suited for structural biology studies. Of course the great restaurants here and close proximity to outdoorsy activities like hiking don’t hurt," Cate said. New Faculty Members Bridge Chemistry and Biology Matt Francis: Designer Proteins Assistant Professor Matthew (Matt) Francis is a familiar face to the chemistry department. Francis has spent the last two years as a postdoctoral fellow with Professor Jean Fréchet, designing new polymers to improve existing methods of drug delivery and developing methods to attach them to strands of DNA. “There are lots of variables to take into account,” Francis explained. “But I have always been interested in building and engineering, and I think doing organic synthesis is like being an architect. You first learn the basic tools and reactions that can be used to construct very complex structures.” Growing up in rural Ohio, Francis received his B.S. in chemistry from Miami University in 1994. He obtained his Ph.D. in 1999 at Harvard University, studying asymmetric catalysis under Prof. Eric Jacobsen, before assuming his postdoctoral position here. “I was delighted to have the opportunity to continue here as a faculty member because of the diversity of the research that occurs on campus and in the college. Berkeley offers a tremendous opportunity for collaborations,” Francis said. Chemistry is becoming increasingly interdisciplinary and the more diversity in a department, the stronger that department is, Francis believes. “I realized that organic chemists are in a “My goal as a facunique position to combine the two fields of ulty member is to materials and biology.” continue to branch out as a chemist and choose projects that stretch the boundaries of chemistry into other fields. After graduate school, I thought that as a synthetic chemist I had to choose whether to expand into materials science or biology. But as I progressed in my studies and research, I realized that organic chemists are in a unique position to combine the two fields of materials and biology. So far it has been fun to bridge these traditionally distinct disciplines,” Francis remarked. According to Francis, finding new ways to construct a molecule is quite a challenge. “In the Fréchet group, we did a lot of work constructing conjugates of DNA with polymers known as dendrimers, which are well-defined branched polymers with many interesting uses,” he said. “The DNA portion selfassembles, taking the shape of a doublehelix. And that got me thinking about where synthesis should go, especially with nanoscale materials. Can self-assembly be harnessed to synthesize molecules on a length scale compatible with nanoscale science? Self-assembling proteins have well-defined side chains that can be modified, allowing us to add new functions, with a growth mechanism built right in. If we can harness that property and control where the protein polymers begin and end, we can use that knowledge to build useful things such as circuits.” Another aspect of self-assembling proteins is that they assemble in complex three-dimensional patterns that are incredibly difficult to synthesize with standard technology. “I intend to use the selfassembling proteins of viruses and modify those proteins on both their inner and outer surfaces,” Francis said. In nature these viral proteins assemble into different geometries, one of the most familiar of which is the icosahedron, which has twenty sides. If we can place short polymers on the outside of these structures without affecting their ability to assemble, we could effectively discourage an undesired immune response in drug delivery applications. We could also modify these proteins to carry drug molecules inside the protein shell, effectively making the virus a Trojan horse. The drugs would be encapsulated and delivered using vectors already used by nature.” “I plan to isolate proteins from natural sources and then carry out synthesis on the surface,” Francis stated. “This path could lead to whole new types of devices and methodologies. There is a lot of excitement in the scientific community about nanoscale science because it is brand new, but where nanoscale science will go in the future is impossible to say.” Contemplating his future endeavors, Francis remarked, “In my research, I would like to look back someday and realize that I have helped develop a toolkit that allows researchers to access selfassembling proteins and control them in useful ways. Materials scientists are conventionally thought of as shrinking things down to make such things as faster microprocessors, and this has proven to be a very important challenge. But there are a lot of other interesting things that we could do by building from the ground up.” “In my spare time (I have spare time?) my wife and I enjoy doing outdoor things, such as camping, hiking and backpacking. I also enjoy cooking. My best recipe is a dry gin martini, two olives, straight up, though I suppose I shouldn’t tell incoming students that!” Francis laughed. www.cchem.berkeley.edu 3 New Faculty Members Bridge Chemistry and Biology Jay Groves: How Cells Recognize Each Other Groves studies how cells recognize each other. “Cell membrane recognition is involved in such phenomena as cell signaling, the immune system, and development,” he explained. “As a faculty member, I will develop new strategies to image and study the dynamic spatial organization of molecular components in cell membranes. The membrane is an attractive object of study because it is a two-dimensional fluid embedded in a three-dimensional space. Also, membranes are the definitive organizational motif for life. I think we can learn a lot about how a collection of molecules comes to life by studying membranes. We are one of the only groups approaching this topic from a physical chemistry point of view. Until recently it has been the domain of cell biologists.” and structure on lipid membranes,” he said. This is a fairly general technique that yields lipid membranes with precisely defined patterns. “The aim of this research is to develop micropatterned membranes and other more general structures to help us study the role of dynamic organization in cell membranes. This project involves a combination of several rather different technologies. First, conventionally microfabricated substrates are used to guide the assembly of membranes and proteins into desired geometries. These hybrid bio-solid-state structures are then used to study proteins and living cells.” Peg Skorpinski Though he has been on the faculty since summer of 2000, Assistant Professor Jay Groves is considered a recent addition to the chemistry department. He spent his first year as a professor on leave to complete a fellowship at the Lawrence Berkeley National Labs. “I was halfway through my appointment as a Division Director’s Fellow, which has a two-year appointment. It is a recently created fellowship initiated by Graham Fleming and proved to be a really great experience for me,” Groves said. “I find it fascinating that the cell can take a few simple interactions and use them to form complex behavior,” Groves said. There are a relatively small number of chemical interactions that occur on the cell surface, and cells use this limited repertoire to recognize and communicate with each other extremely accurately. Scientists on the campus are investigating many of these interactions. “I chose to come to Berkeley because it has the strongest chemistry department in the country and is very strong in physical chemistry,” he explained. “The department has the facilities and the resources I need, and it is constantly attracting outstanding students and researchers.” Working with collaborators, including Chemical Engineering Chair Arup Chakraborty, Groves has uncovered a novel mechanism that immune cells use to respond to specific arrangements of cell surWhen he is not doing science, and sometimes when he is, Groves face proteins. “We discovered the interesting fact that immune travels around the world.

The Rockefeller Institute is a small community that trains only graduate students. I found that I wanted to teach undergraduate courses, which I enjoyed doing when I was a graduate student. Also, the research at the Rockefeller Institute is focused primarily on biological issues, which suited me fine for quite a while. But I am at a point in my career where I want to better integrate chemistry and biology, and Berkeley is renowned for the close interaction between the two disciplines,” he explained. In the past ten years, laboratories around the world, including Kuriyan’s, have made amazing progress using molecular and cell biology and X-ray diffraction to determine the structures of complex protein assemblies at atomic resolutions not thought possible by previous generations. “We can study signaling processes and proteins involved in DNA replication, the copying of DNA by the cell before it divides, at less than 3 Å,” he said. “We can gain a lot of useful knowledge by knowing a protein’s structure. I am interested in complementing the structural data with more functional analyses. I want to know how certain proteins known as motor proteins use chemical energy to change the structure of other proteins and effect major changes.” Kuriyan studies the molecular machines and switches that carry out signaling and DNA replication in the cell. Molecular biologists have determined many of the genes and proteins involved in cell signaling, according to Kuriyan. The next step is to understand what regulates the interaction between different molecules. “The challenge of studying cell signaling is that we essentially do not understand the grammar and spelling of cell communication, but we know which letters they use,” he said, comparing cell signaling to language. “Our laboratory focuses on how phosphorylation influences the properties of proteins,” he said. Phosphorylation is the process in which a signaling protein known as a kinase adds a small chemical group to its target protein, thus changing its shape and its ability to function. “The signaling proteins we study include kinases such as Abl and Src. Kinases are crucial in signal transduction path- ways that control cell growth, cell death and other processes,” Kuriyan noted. “My lab, along with Stephen Harrison’s at Harvard, determined the first three-dimensional structure of c-src, a kinase important in the development of certain cancers such as breast and colon. We plan to do computer modeling as well as mutagenesis studies to better understand c-src and other kinases,” he said. In one recent study, Kuriyan and colleagues used x-ray crystallography to discover how the anticancer drug STI-571 from Novartis Pharmaceuticals Corporation inhibits the Abl kinase. In chronic myelogenous leukemia (CML), the Abl kinase, which is normally a well-behaved cellular switch, becomes over activated by a rearrangement of chromosomes during blood cell development. The genes Abl and Bcr are normally found on two different chromosomes. However, these chromosomes can become “The challenge of studying linked together, resulting in a cell signaling is that we fusion Bcr-Abl enzyme that essentially do not understand stimulates white blood cells the grammar and spelling of to grow without any regulacell communication.” tion and leads to leukemia. “The regulation of the Abl kinase has been a major puzzle that we have worked on for many years,” Kuriyan said in a press release by the Howard Hughes Medical Institute. “In particular, we were interested in the fact that although the Abl gene is very similar to the well-known Src family of oncogenes that also produce kinases, the drug STI-571 inhibits Abl but not the Src kinases.” Analysis of the combined structure of STI-571-Abl and the additional biochemical experiments produced some surprising results, Kuriyan continued, because they revealed that STI-571 bound only to inactivated Abl and did not recognize the activated form. The studies showed that STI-571 targeted the Abl protein only when a key Abl structure, called an activation loop, was shut down. “Basically, we demonstrated that STI-571 is binding to Abl in its off position, but not when the activation loop is in its on position,” said Kuriyan. Thus, he emphasized, the drug’s preference for Abl over Src can be explained by the difference in the shapes of inactivated Abl and Src. In his move out west, Kuriyan is actually uprooting sixteen people from Rockefeller, as well as his family and his dogs. Currently shuttling back and forth between Berkeley and New York, Kuriyan will settle here in October. www.cchem.berkeley.edu 5 New Faculty Members Bridge Chemistry and Biology Michael Marletta: NO toxicity? No problem Professor Michael Marletta is in the process of moving his lab to Berkeley from the University of Michigan. Marletta , recently elected a fellow of the American Academy of Arts and Sciences, is eager to begin his research here. “I am really excited to be back in the Bay Area. I received my Ph.D. from UCSF and fell in love with this part of the country years ago. It's hard not to love it here.” “The main project in the lab is the study of nitric oxide (NO) as an intracellular signaling agent,” Marletta said. NO serves many functions in the body, such as causing blood vessels to dilate, and it is capable of killing bacteria, fungi, and even tumor cells. However, it is also very dangerous at high levels because it is a toxic nitrogen free radical. NO can actually kill neurons and is thought to be responsible for much of the degeneration that occurs after strokes and in some neurological diseases such as Huntington’s and Alzheimer’s. “The idea that nature would use a toxic agent such as NO as a signaling agent was considered preposterous until the science was worked out in the mid-to-late '80s,” he remarked. “However, we now know that NO plays an extensive and important role in mammalian biochemistry,” Marletta explained. “What I want to understand is how exactly NO works: how the enzyme nitric oxide synthase forms NO, how NO finds its target, which happens to be another enzyme, how the binding of NO occurs, and how the receptors in the cell bind and distinguish NO from other small compounds, such as O2. My lab is working out the many questions of NO signaling at the molecular and atomic levels.” “We are also studying how NO is used by humans as a protection against invading bacteria. Say you cut yourself chopping onions: bacteria enter the cut and start multiplying. But white blood cells in your immune system bombard those bacteria with several noxious chemical compounds including NO and kill the bacteria,” Marletta continued. “However, many pathogens, such as Mycobacterium tuberculosis, are resistant to NO. We are gathering evidence that these pathogens contain enzymes that can degrade NO and detoxify it. If we understand how these enzymes thwart NO toxic- ity, we can work toward better treatments for diseases such as tuberculosis,” he said. Another project Marletta is pursuing involves the formation of hemozoin by the malarial parasite. “The Plasmodium parasite that causes malaria spends time in red blood cells, where it degrades hemoglobin and uses the waste as a source of nutrition. The heme molecule, which consists of a protoporphyrin ring and a central iron (Fe) atom, is liberated from hemoglobin and would normally be toxic to the parasite. But the malaria parasite contains an unusual protein, the histidine-rich protein (HRP), which polymerizes the heme to form hemozoin. And hemozoin is relatively harmless,” he said. “I would like to understand what happens when this protein binds to heme, how it polymerizes it to a nontoxic compound.” According to Marletta, the HRP initially starts out in a random coil configuration. However as it binds to heme, it slowly adopts an unusual 3-10 helix conformation. “By modeling this binding, we can determine which histidine residues are needed for the HRP to bind the heme,” he continued. This line of questioning could lead to better antimalarial drugs and help eradicate a disease responsible for more than two million deaths a year. “My lab is working out the many questions of NO signaling at the molecular and atomic levels.” “I am looking forward to doing science at Berkeley. The scientific environment here was a big draw,” Marletta said. “And Berkeley has put into place several initiatives that indicate a willingness to accommodate faculty working at the interfaces of the traditional disciplines, such as chemistry and biology.” “My lab asks chemical questions about biological problems. I think this is exactly the right time when the interface between chemistry and biology will really blossom and come into its own,” he said. “Many scientists might think I have a screw loose,” laughed Marletta. “After all, I gave up a Howard Hughes Investigator position to come here. But I was really attracted to this position because of the tremendous strength of the chemistry department and because I am a firm believer that the real excitement in research is at the interface of the traditional disciplines.” Marletta also has appointments in Molecular and Cell Biology and at UCSF. The NEWSLETTER OF THE COLLEGE OF CHEMISTRY at Berkeley is published several times each year to support the College’s mission of providing excellent teaching, research and public service in the fields of Chemistry and Chemical Engineering.
