Function

[AMPM2_MYCTU] Removes the N-terminal methionine from nascent proteins, when the penultimate amino acid is alanine or proline, but enzyme activity is remarkably low when the second residue is phenylalanine or leucine. With glycine at the second position, Map is more active with a tetrapeptide than with a tripeptide.[1] [2]
