RESUMO
After preliminary assays, with papain, bromelain and ficin, on a range of citrulline p-nitroanilides, values of Km and kcat. for the papain-catalysed hydrolysis of three derivatives, N alpha- benzyloxycarbonylcitrulline p-nitroanilide, benzyloxycarbonylphenylalanylcitrulline p-nitroanilide and benzyloxycarbonylglycylphenylalanylcitrulline p-nitroanilide, were obtained. It is concluded that benzyloxycarbonylphenylalanylcitrulline p-nitroanilide is a highly selective substrate for the sensitive detection and assay of the plant cysteine proteinases.
