EC 3.5.5.7 Details

show Brenda entry

EC number

3.5.5.7

Accepted name

aliphatic nitrilase

Reaction

R-CN + 2 H₂O = R-COOH + NH₃

Systematic name

aliphatic nitrile aminohydrolase

CAS registry number

395644-15-2

Comment

Preferentially hydrolyses aliphatic nitriles, some of which are apparently not substrates for other known nitrilases (EC 3.5.5.1). Substrates include crotononitrile, acrylonitrile and glutaronitrile.
