Nitrate respiration catalysed by the epsilon-proteobacterium Wolinella succinogenes relies on the NapAGHBFLD system that comprises periplasmic nitrate reductase (NapA) and various other Nap proteins required for electron transport from menaquinol to NapA or maturation of Nap components. The W. succinogenes Nap system is unusual as electron transfer to NapA was shown previously to depend on both subunits of the predicted menaquinol dehydrogenase complex NapGH but did not require a cytochrome c… CONTINUE READING
