Dr. Chitta Das -- Assistant Professor-Biochemistry, Department of Chemistry, Purdue University, will present a seminar titled "Regulation of Catalytic Activity of Deubiquitinating Enzymes" on Tues. Nov. 27 at 4 p.m.

Das studies structure and mechanism of a novel group of enzymes called deubiquitinases that make ubiquitination a reversible process. The structural knowledge can be used for structure based inhibitor design with potential application in development of therapeutics.
