Protein attributes

Sequence length	169 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Removes the formyl group from the N-terminal Met of newly synthesized proteins. Requires at least a dipeptide for an efficient rate of reaction. N-terminal L-methionine is a prerequisite for activity but the enzyme has broad specificity at other positions By similarity. HAMAP MF_00163
Catalytic activity	Formyl-L-methionyl peptide + H2O = formate + methionyl peptide. HAMAP MF_00163
Cofactor	Binds 1 Fe2+ ion By similarity. HAMAP MF_00163
Sequence similarities	Belongs to the polypeptide deformylase family.
