The cbb3-type cytochrome c oxidase from Rhodobacter sphaeroides, a proton-pumping heme-copper oxidase.

Biochimica et biophysica acta - 20 Jul 1998

Abstract excerpt

Rhodobacter sphaeroides expresses a bb3-type quinol oxidase, and two cytochrome c oxidases: cytochrome aa3 and cytochrome cbb3. We report here the characterization of the genes encoding this latter oxidase. The ccoNOQP gene cluster of R. sphaeroides contains four open reading frames with high similarity to all ccoNOQP/fixNOQP gene clusters reported so far. CcoN has the six highly conserved histidines proposed to...
