Accepted name
caldariellaquinol oxidase (H+-transporting)
2 caldariellaquinol + O2 + n H+[side 1] = 2 caldariellaquinone + 2 H2O + n H+[side 2]
Other name(s)
SoxABCD quinol oxidase, SoxABCD complex, quinol oxidase SoxABCD, SoxM supercomplex, aa3-type quinol oxidase, aa3 quinol oxidase, cytochrome aa3, terminal quinol oxidase, terminal quinol:oxygen oxidoreductase, caldariella quinol:dioxygen oxidoreductase, cytochrome aa3-type oxidase, caldariellaquinol:O2 oxidoreductase (H+-transporting)
Systematic name
caldariellaquinol:oxygen oxidoreductase (H+-transporting)
A copper-containing cytochrome. The enzyme from thermophilic archaea is part of the terminal oxidase and catalyses the reduction of O2 to water, accompanied by the extrusion of protons across the cytoplasmic membrane.
