Linked to oxidoreductase reactions
Sysname
caldariellaquinol:oxygen oxidoreductase (H+-transporting)
Reaction(IUBMB)
2 caldariellaquinol + O2 + n H+[side 1] = 2 caldariellaquinone + 2 H2O + n H+[side 2] [RN:R10444]
Reaction(KEGG)
R10444
Substrate
caldariellaquinol [CPD:C20623];
O2 [CPD:C00007];
H+[side 1]
Product
caldariellaquinone [CPD:C20624];
H2O [CPD:C00001];
H+[side 2]
Comment
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.
