IUBMB Enzyme Nomenclature


Accepted name: aliphatic nitrilase

Reaction: R-CN + 2 H2O = R-COOH + NH3

Systematic name: aliphatic nitrile aminohydrolase

Comments: preferentially hydrolyses aliphatic nitriles, some of which are apparently not substrates for other known nitrilases (EC Substrates include crotononitrile, acrylonitrile and glutaronitrile.
