摘要

Abstract: This paper describes the mechanistic investigation of a-chymotrypsin and [Met, 9z- sulfoxide]-a-chymotrypsin-catalyzed peptide synthesis in a kinetically controlled process (Le., aminolysis) and the relative stabilities of both enzymes in different conditions. Partitioning parameters for various nucleophiles (including D-and L-amino acids) competing with water for the acyl enzyme intermediate were determined. These parameters provide ...
