Penicillin acylase from Alcaligenes faecalis catalyzes the enantioselective acylation of amines with phenylacetamide in a kinetically controlled reaction in water at pH II. Addition of cosolvent to the reaction mixture significantly improved the enantioselectivity in most cases. Penicillin acylase from E. coli also catalyzed the phenylacetylation of amines, but an order of magnitude less efficiently than with the enzyme of A. faecalis. Amine resolution via kinetically controlled acylation competes effectively with hydrolysis of N-acylated compounds and constitutes a synthetically useful alternative to existing lipase-based methods.
