nitric oxide + H2O + ferricytochrome c = nitrite + ferrocytochrome c + 2 H+
reaction mechanism, overview. Mobility of two residues essential to catalytic activity, Asp98 and His244, are sterically restricted in GtNIR by Phe109 on a characteristic loop structure that is found above Asp98 and by an unusually short CH-O hydrogen bond observed between His244 and water, respectively. Analysis of the hydrogen-bond networks around His244 and the flow path of protons consumed by nitrite reduction. The electron transfer reaction is coupled with the proton transfer reaction
nitric oxide + H2O + ferricytochrome c = nitrite + ferrocytochrome c + 2 H+
reaction mechanism, overview. The transformation from the initial O-coordination of substrate to the final N-coordination of product is achieved by electron transfer from T1 copper to T2 copper, rather than by the previously reported side-on coordination of a NO intermediate, which only takes place in the reduced enzyme. Role of structural change in the critical residue Asp98, which affects the energetics of substrate attachment and product release at the T2 copper reaction center, while it does not significantly affect the activation energy and reaction pathways of the nitrite reduction process
nitric oxide + H2O + ferricytochrome c = nitrite + ferrocytochrome c + 2 H+
the proposed mechanisms for the reduction of nitrite by CuNiRs include intramolecular electron and proton transfers, proton-coupled electron transfer is one of the key processes in enzyme reactions, density functional theory calculations analysis. The reduction of T2 Cu site promotes the proton transfer, and the hydrogen bond network around the binding site has an important role not only to stabilize the nitrite binding but also to promote the proton transfer to nitrite.
