|Rhodococcus rhodochrous :||aliphatic nitrilase
In Pathway: acrylonitrile degradation II
Note that this reaction equation differs from the official Enzyme Commission reaction equation for this EC number, which can be found here .
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
Mass balance status: Balanced.
Enzyme Commission Primary Name: aliphatic nitrilase
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): -3.7801266 [Latendresse13]
The enzyme preferentially hydrolyses aliphatic nitriles, some of which are apparently not substrates for other known nitrilases (EC 18.104.22.168). Substrates include crotononitrile, acrylonitrile and glutaronitrile.
This reaction is different from EC 22.214.171.124 in that the substrates for this reaction must be aliphatic.
Enzyme Commission Summary:
Preferentially hydrolyses aliphatic nitriles, some of which are apparently not substrates for other known nitrilases (EC 126.96.36.199). Substrates include crotononitrile, acrylonitrile and glutaronitrile.
