IUBMB Enzyme Nomenclature


Accepted name: cyanoalanine nitrilase

Reaction: 3-cyano-L-alanine + 2 H2O = L-aspartate + NH3 (overall reaction)
(1a) 3-cyano-L-alanine + H2O = L-asparagine
(1b) L-asparagine + H2O = L-aspartate + NH3

Other name(s): β-cyanoalanine nitrilase

Systematic name: 3-cyano-L-alanine aminohydrolase

Comments: L-Asparagine is formed as an intermediate. cf. EC, 3-cyanoalanine hydratase and EC, asparaginase.
