Cytochrome b6f oxidizes
WebThe enzyme cytochrome c oxidase or Complex IV, (was EC 1.9.3.1, now reclassified as a translocase EC 7.1.1.9) is a large transmembrane protein complex found in bacteria, archaea, and mitochondria of eukaryotes. [1] It is the last enzyme in the respiratory electron transport chain of cells located in the membrane.
