The leader peptide of bacteriophage M13 procoat inhibited the cleavage of M13 procoat or pre-maltose-binding protein by purified Escherichia coli leader peptidase. This finding confirms inferences that the leader is the primary site of enzyme recognition and suggests a rationale for the rapid hydrolysis of leader peptides in vivo.
