The transition-state analogues bis(p-nitrophenyl)phosphate and p-nitrophenyl phenylphosphonate for peptide hydrolysis are shown to be very effectively hydrolyzed by Streptomyces dinuclear aminopeptidase and its Co2+, Ni2+, Mn2+ and Cd2+ derivatives with high catalytic proficiencies and specific activities comparable to those of some phosphoesterases.
