A colorless solid, it is produced by ammoxidation of 3-methylpyridine: [2] H 3 CC 5 H 4 N + NH 3 + 1.5 O 2 → NCC 5 H 4 N + 3 H 2 O. Nicotinonitrile is a precursor to the vitamin niacin. [3] Nitrilase-catalyzed hydrolysis of 3-cyanopyridine by means of immobilized Rhodococcus rhodochrous J1 [2] strains leads in quantitative yield to ...
Nitrilase was first discovered in the early 1960s for its ability to catalyze the hydration of a nitrile to a carboxylic acid. [2] Although it was known at the time that nitrilase could operate with wide substrate specificity in producing the corresponding acid, later studies reported the first NHase (nitrile hydratase) activity exhibited by nitrilase.
Nitrile hydratase and amidase are two hydrating and hydrolytic enzymes responsible for the sequential metabolism of nitriles in bacteria that are capable of utilising nitriles as their sole source of nitrogen and carbon, and in concert act as an alternative to nitrilase activity, which performs nitrile hydrolysis without formation of an intermediate primary amide.

In enzymology, an aliphatic nitrilase also known as aliphatic nitrile aminohydrolase (EC 3.5.5.7) is an enzyme that catalyzes the hydrolysis of nitriles to carboxylic acids: R-CN + 2 H 2 O ⇌ {\displaystyle \rightleftharpoons } R-COOH + NH 3
