dc.description.abstract | Recently, we reported (1) that the stoichiometry of proton pumping is about 0.4–0.5 proton per electron for members of the C family of respiratory oxygen reductases, also called the cbb3-type cytochrome c oxidases. This amount (0.5) is about half of the value obtained with the canonical A family of respiratory oxygen reductases, which includes the mitochondrial cytochrome c oxidases. We pointed out that the low stoichiometry correlates with the absence of the D channel for proton input and speculated that these properties may be an evolutionary adaptation to aerobic respiration under conditions of low oxygen. | en_US |
