Steven G. Clarke, (born November 19, 1949) an American biochemist, is a director of the UCLA Molecular Biology Institute, [1] a professor of chemistry and biochemistry at UCLA biochemistry department. Clarke heads a laboratory at UCLA's department of chemistry and biochemistry. Clarke is famous for his work on molecular damage and discoveries of novel molecular repair mechanisms.

Contents

Clarke has been on the faculty of the UCLA Department of Chemistry and Biochemistry since 1978. He is currently a professor of biochemistry and director of the UCLA Molecular Biology Institute.

Early life and education

He was born in Los Angeles and attended public schools in Altadena and Pasadena, California.

He did his undergraduate work at Pomona College, a private institution, in Claremont, majoring in Chemistry and Zoology and graduating in 1970. [2] During this time, he did undergraduate research at the UCLA Brain Research Institute with James E. Skinner and Professor Donald B. Lindsley on neural mechanisms of attention. He was also an NIH fellow in the laboratory of Peter Mitchell at Glynn Research Laboratories in Bodmin, England studying mitochondrial amino acid transport.

He obtained a PhD in biochemistry and molecular biology from Harvard University working as an NSF Fellow with Professor Guido Guidotti on membrane protein-detergent interactions and the identification of the major rat liver mitochondrial polypeptides as enzymes of the urea cycle. He returned to California to do postdoctoral work as a Miller Fellow at the University of California, Berkeley, with Professor Daniel Koshland, identifying membrane receptors for bacterial chemotaxis.

Career

Clarke's research at UCLA has focused on roles of novel protein methyltransferases in aging and biological regulation highlighted by discoveries of the protein repair L-isoaspartyl methyltransferase, [3] the isoprenylcysteine protein methyltransferase, [4] and the protein phosphatase 2A methyltransferase. [5]

He was a visiting scholar at Princeton University (1986–87) and at the University of Washington (2004-2005).

Clarke has conducted research on the biochemistry of brains and Alzheimer's disease [6] since 1990. [7]

In biochemistry, dephosphorylation is the removal of a phosphate (PO43−) group from an organic compound by hydrolysis. It is a reversible post-translational modification. Dephosphorylation and its counterpart, phosphorylation, activate and deactivate enzymes by detaching or attaching phosphoric esters and anhydrides. A notable occurrence of dephosphorylation is the conversion of ATP to ADP and inorganic phosphate.

He contributed many key experimental and theoretical results and developed new methods, garnering over 20,000 journal citations in several quite distinct research areas. In addition to the protein crystallography and biochemistry of ribonuclease S, these included solvent accessibility and internal packing of proteins, the first side-chain rotamer library, high-pressure crystallography, new types of chemical tags such as biotin/avidin, the nuclear magnetic resonance (NMR) chemical shift index, and structural and biophysical characterization of the effects of mutations.

Subsequently, Fridovich's research group also discovered the manganese-containing and the iron-containing SODs from Escherichia coli and the mitochondrial MnSOD (SOD2), now known to be an essential protein in mammals. He spent the rest of his career studying the biochemical mechanisms of SOD and of biological superoxide toxicity, using bacteria as model systems. Fridovich was also Professor Emeritus of Biochemistry at Duke University.
