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. Source: Recombinant protein corresponding to aa1-266 from Mycobacterium tuberculosis Methionine aminopeptidase 1, fused to 6X His-Tag at N-terminal, expressed in E.coli.
