[[http://www.uniprot.org/uniprot/AMPM2_MYCTU 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.<ref>PMID:19688379</ref> <ref>PMID:20038112</ref>
[https://www.uniprot.org/uniprot/MAP12_MYCTU MAP12_MYCTU] Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed.[HAMAP-Rule:MF_01974]<ref>PMID:19688379</ref> <ref>PMID:20038112</ref>
