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.
Catalytic activity RHEA:24420: H2O + N-terminal N-formyl-L-methionyl-[peptide] = formate + N-terminal L-methionyl-[peptide]
EC 3.5.1.88
case <FTGroup:1>
Cofactor Fe(2+)
Note: Binds 1 Fe(2+) ion.
end case
Similarity Belongs to the polypeptide deformylase family.
