EC 3.5.5.4
Names
Accepted name:
cyanoalanine nitrilase
Other
name:
β-cyanoalanine nitrilase
Systematic name:
3-cyano-L-alanine aminohydrolase
Reactions
- (1) 3-cyano-L-alanine + 2 H2O = L-aspartate + NH3
- (1a) 3-cyano-L-alanine + H2O = L-asparagine
- (1b) L-asparagine + H2O = L-aspartate + NH3
Comments:
L-Asparagine is formed as an intermediate. cf. EC 4.2.1.65, 3-cyanoalanine hydratase and EC 3.5.1.1, asparaginase.
