| 7.2.1.2 | metabolism |
methanogenesis from acetate by Methanosarcina acetivorans involves an anaerobic electron transport chain with ferredoxin as electron donor and heterodisulfide as electron acceptor. Proposed model of the aceticlastic pathway of methanogenesis in Methanosarcina acetivorans, overview |

| 7.2.1.2 | metabolism |
role of the enzyme Rnf complex in the Wood-Ljungdahl pathway, overview. Acetogens use the WoodLjungdahl pathway for reduction of carbon dioxide to acetate. This pathway not only allows reoxidation of reducing equivalents during heterotrophic growth but also supports chemolithoautotrophic growth on H2 +CO2. In addition to CO2, acetogens can use alternative electron acceptors, such as nitrate or caffeate. Caffeate respiration in the model acetogen Acetobacterium woodii is coupled to energy conservation via a chemiosmotic mechanism, with Na+ as coupling ion. Coupling of the Wood-Ljungdahl pathway to primary and electrogenic translocation of Na+ across the cytoplasmic membrane in Acetobacterium woodii |

| 7.2.1.2 | metabolism |
the constitutive production argues for an involvement of the Rnf complex not only in caffeate respiration but also in general metabolism |

| 7.2.1.2 | metabolism |
