IntEnz Enzyme Nomenclature


Accepted name:
peptide deformylase
Other names:
polypeptide deformylase
Systematic name:
formyl-L-methionyl peptide amidohydrolase




Requires Fe(II). Also 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. Differs in substrate specifity from EC (formylmethionine demethylase).
