Hydrogen is a preferred intermediate in the energy-conserving electron transport chain of Methanosarcina barkeri.

Proceedings of the National Academy of Sciences of the United States of America - 15 Sept 2009

Abstract excerpt

Methanogens use an unusual energy-conserving electron transport chain that involves reduction of a limited number of electron acceptors to methane gas. Previous biochemical studies suggested that the proton-pumping F(420)H(2) dehydrogenase (Fpo) plays a crucial role in this process during growth on methanol. However, Methanosarcina barkeri Delta fpo mutants constructed in this study display no measurable...
