Protein
Methionine aminopeptidase C
Organism
Synechocystis sp. (strain PCC 6803 / Kazusa)
Function
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.
Similarity
Belongs to the peptidase M24A family. Methionine aminopeptidase type 1 subfamily.
