The goal of this research is to engineer enzymes to be efficient and economically attractive catalysts for the chemical industry. The author is attempting to demonstrate generally-applicable approaches to enzyme improvement as well as develop specific catalysts for potential industrial application. The research is focused on the following areas: (1) Random mutagenesis of pNB esterase: improved activity and stability; (2) Directed evolution of subtilisin E to enhance thermostability; and (3) Methods for in vitro recombination
