<unk> s (EC 1.10.3.-) are enzymes in the bacterial electron transport chain that<unk> <unk>  into<unk> e and reduce oxygen to water. These enzymes are one set of the many alternative terminal<unk> s in the branched prokaryotic electron transport chain. The overall structure of the E. coli<unk>  is similar to that of the mammalian Cytochrome c<unk> , with the addition of a polar<unk> -binding site embedded in the membrane.
