Conserved hypothetical cytochrome c oxidase,subunit II; Subunits I and II form the functional core of the enzyme complex. Electrons originating in cytochrome c are transferred via heme a and Cu(A) to the binuclear center formed by heme a3 and Cu(B).

Cytochrome c oxidase polypeptide III Subunits I II and III form the functional core of the enzyme complex. InterPro: Cytochrome c oxidase subunit III; High confidence in function and specificity.

Ubiquinol-cytochrome c reductase cytochrome b protein; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis.

Putative NADH-ubiquinone oxidoreductase chain A; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; Belongs to the complex I subunit 3 family.

Putative protoheme IX farnesyltransferase; Converts heme B (protoheme IX) to heme O by substitution of the vinyl group on carbon 2 of heme B porphyrin ring with a hydroxyethyl farnesyl side group.

Putative NADH-ubiquinone oxidoreductase, chain M; NADH-quinone oxidoreductase chain M (EC 1.6.99.5) (NADH dehydrogenase I chain M) (NDH-1 chain M). NDH-1 shuttles electrons from NADH via FMN and iron- sulfur (Fe-S) centers to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred four hydrogen ions are translocated across the cytoplasmic membrane) and thus conserves the redox energy in a proton gradient. InterPro: NADH-Ubiquino [...]

NADH-ubiquinone oxidoreductase, chain N probable; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient.; Belongs to the complex I subunit 2 family.

Putative NADH-ubiquinone oxidoreductase chain H; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient. This subunit may bind ubiquinone.
