Accepted name: aminopeptidase Y
Reaction: Preferentially, release of N-terminal lysine
Other name(s): aminopeptidase Co; aminopeptidase (cobalt-activated); lysyl aminopeptidase
Comments: Requires Co2+; inhibited by Zn2+ and Mn2+. An enzyme best known from Saccharomyces cerevisiae that hydrolyses Lys-NHPhNO2 and, more slowly, Arg-NHPhNO2. Type example of peptidase family M28
