Nitrite reduction by copper through ligand-mediated proton and electron transfer.
نویسندگان
چکیده
Nitrite reduction by a copper complex featuring a proton-responsive tripodal ligand is demonstrated. Gaseous nitric oxide was confirmed as the sole NO X by-product in quantitative yield. DFT calculations predict that nitrite reduction occurs via a proton and electron transfer process mediated by the ligand. The reported mechanism parallels nitrite reduction by copper nitrite reductase.

Nitrite reductases (NiRs) are enzymes found in prokaryotic organisms which catalyze the one-electron (e ) reduction of nitrite to nitric oxide (NO). Copper nitrite reductases (CuNiRs) are homotrimeric enzymes with each monomer containing two copper centers: a T1 site for electron transfer, and a catalyticallyactive T2 site. Although X-ray crystallographic studies have provided structural snapsh...
متن کاملGating mechanisms for biological electron transfer: integrating structure with biophysics reveals the nature of redox control in cytochrome P450 reductase and copper-dependent nitrite reductase.
Biological electron transfer is a fundamentally important reaction. Despite the apparent simplicity of these reactions (in that no bonds are made or broken), their experimental interrogation is often complicated because of adiabatic control exerted through associated chemical and conformational change. We have studied the nature of this control in several enzyme systems, cytochrome P450 reducta...
متن کاملApplication of copper oxide nanoparticles modified glassy carbon electrode for electrocatalytic oxidation of methanol
Copper nanoparticles were fabricated by electro-reduction of CuSO4solution in the presence of cetyltrimethylammonium bromide (CTAB) cationic surfactant as an additive through potentiostatic method. The prepared copper nanoparticles were characterized by scanning electron microscopy (SEM) and electrochemical methods. The SEM images reveal that the nanoparticles with diameters at about 70 n...
متن کاملRedox-coupled proton transfer mechanism in nitrite reductase revealed by femtosecond crystallography.
Proton-coupled electron transfer (PCET), a ubiquitous phenomenon in biological systems, plays an essential role in copper nitrite reductase (CuNiR), the key metalloenzyme in microbial denitrification of the global nitrogen cycle. Analyses of the nitrite reduction mechanism in CuNiR with conventional synchrotron radiation crystallography (SRX) have been faced with difficulties, because X-ray pho...
متن کاملHydrogen Bonding Networks Tune Proton-Coupled Redox Steps during the Enzymatic Six-Electron Conversion of Nitrite to Ammonia
Multielectron multiproton reactions play an important role in both biological systems and chemical reactions involved in energy storage and manipulation. A key strategy employed by nature in achieving such complex chemistry is the use of proton-coupled redox steps. Cytochrome c nitrite reductase (ccNiR) catalyzes the six-electron seven-proton reduction of nitrite to ammonia. While a catalytic m...
