Pehr Harbury is a biochemist who explores the structure,
activity, and synthesis of proteins with the aim of developing more potent and
more specific drugs for the treatment of disease. Early in his career, he
focused on rational protein design, based on first-principles of amino acid
structural chemistry. Most functional proteins consist of amino acid side
chains attached to a protein backbone. Harbury developed a method for
accurately predicting main- and side-chain structures, even for complex multimers.
To demonstrate the power of his calculation, he and his colleagues synthesized
proteins with unnatural, right-handed supercoiled structure and showed that
they were able accurately to predict structures that had never previously
existed. To improve understanding of side-chain functionality, Harbury
developed an assay for testing the interaction of substrate and specific amino
acids. Most recently, Harbury has introduced an efficient and effective method
for using in vitro evolution to control combinatorial synthesis of small
molecules. With this technique, he is able to tether to a single molecule the
information needed to synthesize more of it. When combined with an instruction
set many orders of magnitude larger than previous combinatorial chemical
libraries and a large pool of chemical manipulations compatible with the
process, Harbury's "DNA Display" technique promises vast increases in
the speed, efficiency, and search space for the use of combinatorial chemistry
in the development of new drugs.
Pehr Harbury received a B.A. (1987) and a Ph.D. (1994) from Harvard University. He was a postdoctoral fellow (1995-97) at the University of California, Berkeley, and is currently an associate professor in the Department of Biochemistry
at Stanford University, where he has been on the faculty since 1997. His
publications have appeared in such academic journals as PLoS Biology, Nature,
Science, and Proceedings of the National Academy of Sciences USA.
