In enzymology, an enamidase () is an enzyme that catalyzes the chemical reaction 6-oxo-1,4,5,6-tetrahydronicotinate + 2 H2O 2-formylglutarate + NH3 Thus, the two substrates of this enzyme are 6-oxo-1,4,5,6-tetrahydronicotinate and H2O, whereas its two products are 2-formylglutarate and NH3. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amides. The systematic name of this enzyme class is 6-oxo-1,4,5,6-tetrahydronicotinate amidohydrolase. References EC 3.5.2 Enzymes of unknown structure
