3.4.11.2 | Release of an N-terminal amino acid, Xaa-/-Yaa- from a peptide, amide or arylamide. Xaa is preferably Ala, but may be most amino acids including Pro (slow action). When a terminal hydrophobic residue is followed by a prolyl residue, the two may be released as an intact Xaa-Pro dipeptide |
residues E298 and Y381 located near the zinc ion, are involved in peptide cleavage. Residue M260 functions as a cushion to accept substrates with different N-terminal resiude sizes |
