【 摘 要 】
The sodium-transport respiratory chain NADH:quinone reductase of a marine bacterium, Vibrio alginolyti-cus, is composed of three protein subunits, α,β and γ. The β-subunit contains FAD as a prosthetic group and corresponds to NADH dehydrogenase, which catalyses the reduction of ubiquinone to ubisemiquinone. In addition to β, subunits α. and γ are essential for the quinone reductase, which catalyses the reduction of ubiquinone to ubiquinol. The α-subunit contains FMN and the reaction catalysed by subunit α is related to the coupling site of the sodium pump in the quinone reductase.
