In enzymology, a N-substituted formamide deformylase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are N-benzylformamide and H<sub>2</sub>O, whereas its two products are formate and benzylamine.
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 N-benzylformamide amidohydrolase and is also called NfdA. The enzyme is produced by Arthrobacter pascens bacteria.
