>cd07564 nitrilases_CHs Nitrilases, cyanide hydratase (CH)s, and similar proteins (class 1 nitrilases). Nitrilases (nitrile aminohydrolases, EC:3.5.5.1) hydrolyze nitriles (RCN) to ammonia and the corresponding carboxylic acid. Most nitrilases prefer aromatic nitriles, some prefer arylacetonitriles and others aliphatic nitriles. This group includes the nitrilase cyanide dihydratase (CDH), which hydrolyzes inorganic cyanide (HCN) to produce formate. It also includes cyanide hydratase (CH), which hydrolyzes HCN to formamide. This group includes four Arabidopsis thaliana nitrilases (Ath)NIT1-4. AthNIT1-3 have a strong substrate preference for phenylpropionitrile (PPN) and other nitriles which may originate from the breakdown of glucosinolates. The product of PPN hydrolysis, phenylacetic acid has auxin activity. AthNIT1-3 can also convert indoacetonitrile to indole-3-acetic acid (IAA, auxin), but with a lower affinity and velocity. From their expression patterns, it has been speculated that
