The enzyme 3-cyanoalanine hydratase (EC 4.2.1.65) catalyzes the chemical reaction
This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is L-asparagine hydro-lyase (3-cyanoalanine-forming). Other names in common use include β-cyanoalanine hydrolase, β-cyanoalanine hydratase, β-CNAla hydrolase, β-CNA nitrilase, and L-asparagine hydro-lyase. This enzyme participates in cyanoamino acid metabolism.
Nitrilase enzymes catalyse the hydrolysis of nitriles to carboxylic acids and ammonia, without the formation of "free" amide intermediates. Nitrilases are involved in natural product biosynthesis and post translational modifications in plants, animals, fungi and certain prokaryotes. Nitrilases can also be used as catalysts in preparative organic chemistry. Among others, nitrilases have been used for the resolution of racemic mixtures. Nitrilase should not be confused with nitrile hydratase which hydrolyses nitriles to amides. Nitrile hydratases are almost invariably co-expressed with an amidase, which converts the amide to the carboxylic acid. Consequently, it can sometimes be difficult to distinguish nitrilase activity from nitrile hydratase plus amidase activity.
