Organism
Pyrococcus abyssi (strain GE5 / Orsay)
Function
Nitrilase that hydrolyzes preferentially aliphatic nitriles like malononitrile and fumaronitrile in vitro. These dinitriles are converted to the corresponding monoacid mononitriles, showing the enzyme is regioselective. Cannot hydrolyze compounds with a nitrile group bound to an aromatic ring or amino acid. Its biological role is unknown.
Similarity
Belongs to the carbon-nitrogen hydrolase superfamily.
