The chemistry of nitrosative stress induced by nitric oxide and reactive nitrogen oxide species. Putting perspective on stressful biological situations.

abstract：:[NiFe] hydrogenases catalyze reversible hydrogen production/consumption. The active site of [NiFe] hydrogenases contains a complex NiFe(CN)2CO center, and the biosynthesis/maturation of these enzymes is a complex and dynamic process, primarily involving six Hyp proteins (HypABCDEF). HypA and HypB are involved in the N...
