Abstract: | A new aminopeptidase — aminopeptidase Co — has been detected in the yeast . The enzyme is only active in the presence of Co2+ions. Zn2+- and Mn2+ions are inhibitory. The enzyme activity is also inhibited by chelating agents. Of the p-nitroanilide derivatives tested only those containing basic amino acids are cleaved. |
