The anaerobic methanogenic archaeon Methanosarcina acetivorans lives under extreme energy limitation. Methanogenesis from acetate as carried out by M. acetivorans involves an anaerobic electron transport chain with ferredoxin as electron donor and heterodisulfide as electron acceptor, and so far only the heterodisulfide reductase has been shown to translocate H(+) . Here, we describe a second Na(+) -translocating coupling site in this electron transport chain. Inside-out membrane vesicles of M… CONTINUE READING
