CC   -!- FUNCTION: Removes the formyl group from the N-terminal Met of newly
CC       synthesized proteins. Requires at least a dipeptide for an efficient
CC       rate of reaction. N-terminal L-methionine is a prerequisite for
CC       activity but the enzyme has broad specificity at other positions (By
CC       similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + N-terminal N-formyl-L-methionyl-[peptide] = formate + N-
CC         terminal L-methionyl-[peptide]; Xref=Rhea:RHEA:24420, Rhea:RHEA-

CC   -!- COFACTOR:
CC       Name=Fe(2+); Xref=ChEBI:CHEBI:29033; Evidence={ECO:0000250};
CC       Note=Binds 1 Fe(2+) ion. {ECO:0000250};
CC   -!- SIMILARITY: Belongs to the polypeptide deformylase family.
CC       {ECO:0000305}.
