NITRILE HYDRATASE COMPLEXED WITH NITRIC OXIDE
Overview
The iron-containing nitrile hydratase (NHase) is a photoreactive enzyme, that is inactivated in the dark because of persistent association with NO, and activated by photo-dissociation of NO. The crystal structure at 1.7 A, resolution and mass spectrometry revealed the structure of the non-heme, iron catalytic center in the nitrosylated state. Two Cys residues, coordinated to the iron were post-translationally modified to Cys-sulfenic, and -sulfinic acids. Together with another oxygen atom of the Ser ligand, these modifications induced a claw setting of oxygen atoms capturing an NO, molecule. This unprecedented structure is likely to enable the, photo-regulation of NHase and will provide an excellent model for, designing photo-controllable chelate complexes and, ultimately, proteins.
