[https://www.uniprot.org/uniprot/NHAA_RHOER NHAA_RHOER] NHase catalyzes the hydration of various nitrile compounds to the corresponding amides. Industrial production of acrylamide is now being developed using some of the enzymes of this class.

== Publication Abstract from PubMed ==
 +
The crystal structure of Fe-type nitrile hydratase from Rhodococcus erythropolis AJ270 was determined at 1.3A resolution. The two cysteine residues (alphaCys(112) and alphaCys(114)) equatorially coordinated to the ferric ion were post-translationally modified to cysteine sulfinic acids. A glutamine residue (alphaGln(90)) in the active center gave double conformations. Based on the interactions among the enzyme, substrate and water molecules, a new mechanism of biocatalysis of nitrile hydratase was proposed, in which the water molecule activated by the glutamine residue performed as the nucleophile to attack on the nitrile which was simultaneously interacted by another water molecule coordinated to the ferric ion.
