Criteria For Evolution Of Successful Proteins: Fold Fitness And Domain Dynamics Explored, Tyrel Bryan

Chemistry and Chemical Biology ETDs

The Haloacid Dehalogenase Superfamily (HADSF) is a ubiquitous family of enzyme with more than 32,000 members. A variety of reactions are catalyzed by HAD members, but a majority of HAD members are phosphatases. Dephosphorlyation of organophosphate metabolites are carried out in the conserved Rossmann-like core domain. The Rossman-like core domain houses the conserved active site residues necessary for catalysis and also supports domain inserts associated with substrate binding. This dissertation will focus primarily on investigating fold fitness and domain dynamics of HAD proteins more specifically three C2 capped proteins. The first part will focus on whether or not the prevailing …
