Summary

Research in the Distefano group focuses on the use of organic chemistry to provide insight into mechanism and function in biological systems. Several projects are currently being investigated including (1) mechanism and function of protein prenylation (2) rubber biosynthesis (3) illudin biosynthesis (4) protein-based catalyst design and (5) development of methods for selective protein modification. Two themes unite this diverse range of topics. The

protein prenylation, rubber biosynthesis and illudin biosynthesis projects center around the use farnesyl diphosphate and analogues thereof. The goals of these projects are to identify the enzymes involved in these processes and to understand their chemical mechanisms for the purposes of designing new
therapeutic agents or biocatalytic processes. The catalyst design and protein modification projects both involve the use covalent modification techniques to prepare proteins with either novel catalytic or physical properties. Researchers in the Distefano group use a combination of organic synthesis, protein purification, enzymology and biophysical techniques as they work on these projects. Numerous collaborations are in place with other groups both at the University of Minnesota and other academic and industrial institutions to accomplish the interdisciplinary goals of these projects.
