cytochrome C oxidase subunit IV family protein

Cytochrome c oxidase (COX) is a multi-subunit enzyme complex that catalyses the final step of electron transfer through the respiratory chain on the mitochondrial inner membrane. This family is composed of cytochrome c oxidase subunit 4 from prokaryotes. [1]. 8638158. The whole structure of the 13-subunit oxidized cytochrome c oxidase at 2.8 A. Tsukihara T, Aoyama H, Yamashita E, Tomizaki T, Yamaguchi H, Shinzawa-Itoh K, Nakashima R, Yaono R, Yoshikawa S;. Science 1996;272:1136-1144. (from Pfam)

cytochrome aa3 quinol oxidase subunit IV

This family (QoxD) encodes subunit IV of the aa3-type quinone oxidase, one of several bacterial terminal oxidases [1]. This complex couples oxidation of reduced quinones with the reduction of molecular oxygen to water and the pumping of protons to form a proton gradient utilized for ATP production. aa3-type oxidases contain two heme a cofactors as well as copper atoms in the active site.
