Probing the nitrite and nitric oxide reductase activity of cbb3 oxidase: Resonance Raman detection of a six-coordinate ferrous heme-nitrosyl species in the binuclear b3/CuB center
(2015)In this work we report the first spectroscopic evidence demonstrating that cbb3 oxidase catalyzes the reduction of nitrite to nitrous oxide under reducing anaerobic conditions. The reaction proceeds through the formation ...

Resonance Raman detection of the myoglobin nitrito heme Fe-O-N=O/2-nitrovinyl species: Implications for helix E-helix F interactions
(2015)The description of biological activity in heme proteins responsible for activating small molecules requires identification of ligand movement into the metal and non-metal binding sites. Mechanisms of nitrite reductase ...

The structure of a ferrous heme-nitro species in the binuclear heme a3/CuB center of ba3-cytochrome c oxidase as determined by resonance Raman spectroscopy
(2015)Members of the cytochrome c oxidase family exhibit nitrite reductase activity. In this work, we have characterized a ferrous heme a3-nitro species in ba3-oxidase by resonance Raman spectroscopy. This provides the first ...

The structure of the hyponitrite species in a heme Fe-Cu binuclear center
(2007)NO laughing matter: The enzymatic production of laughing gas (N 2O) from two molecules of NO requires the formation of the N-N bond and the subsequent cleavage of the N-OH bond. Resonance Raman spectroscopic studies have ...
