Аннотация:The computationally designed βD484N mutant of penicillin acylase from Escherichia coli
was shown to be more stable at alkaline conditions, resistant to inactivation by high substrate
concentrations and able to catalyze preparative peptide synthesis in aqueous medium more
effectively. The ability of the βD484N mutant to operate in alkaline aqueous medium allowed to
reach up to 80% yields of D-phenylglycine-derived peptide synthesis from equimolar substrate
mixtures while with the wild type penicillin acylase conversion was below 17%.
