c-type cytochrome
cytochrome c oxidase subunit II transmembrane domain-containing protein
The N-terminal domain of cytochrome C oxidase contains two transmembrane alpha-helices. [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)
The Pfam entry does not include all Prosite members. The cytochrome 556 and cytochrome c' families are not included. All these are now in a new clan together. The C-terminus of DUF989, Pfam:PF06181, has now been merged into this family. (from Pfam)
Cytochrome C oxidase subunit II, periplasmic domain
cytochrome c oxidase subunit II
cytochrome c oxidase subunit II, together with subunit I, forms the functional core of the enzyme that catalyzes the reduction of O2 and simultaneously pump protons across the membrane
Cytochrome c oxidase is the terminal electron acceptor of mitochondria (and one of several possible acceptors in prokaryotes) in the electron transport chain of aerobic respiration. The enzyme couples the oxidation of reduced cytochrome c with the reduction of molecular oxygen to water. This process results in the pumping of four protons across the membrane which are used in the proton gradient powered synthesis of ATP. The oxidase contains two heme a cofactors and three copper atoms as well as other bound ions [1].
