Members of the cytochrome c oxidase family exhibit nitrite reductase activity. In this work, we have characterized a ferrous heme a 3 -nitro species in ba 3 -oxidase by resonance Raman spectroscopy. This provides the first evidence for the structure of a nitrite-bound species in the binuclear heme/c...

Description
Summary:Members of the cytochrome c oxidase family exhibit nitrite reductase activity. In this work, we have characterized a ferrous heme a 3 -nitro species in ba 3 -oxidase by resonance Raman spectroscopy. This provides the first evidence for the structure of a nitrite-bound species in the binuclear heme/copper center of cytochrome c oxidases. We present resonance Raman evidence for the formation of a ferrous heme-nitro species in the binuclear heme/copper center of ba 3 -oxidase.
