Peptide deformylase

In enzymology, a peptide deformylase (EC 3.5.1.88) is an enzyme that catalyzes the chemical reaction

formyl-L-methionyl peptide + H₂O formate + methionyl peptide

Thus, the two substrates of this enzyme are formyl-L-methionyl peptide and H₂O, whereas its two products are formate and methionyl peptide.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is formyl-L-methionyl peptide amidohydrolase.
