Fig. 7: Predicted electromethanogenic pathway of Methanomasilliicoccus luminyensis.

From: Extracellular electron transfer based methylotrophic methanogenesis in paddy soil and the prevalent Methanomassiliicoccus

Fig. 7

Extracellular electrons from C. malenominatum or cathode are accepted by the M. luminyensis Pili and transferred to, or directed accepted by the membrane bound Fpo-like complex. Electrons are then transferred to membrane associated HdrD to reduce heterodisulfide CoM-S-S-CoB for methane production from methanol (MeOH) or trimethylamine (TMA). Protein icons shadowed in purple, blue and gray represent the encoding genes to be up- and down-regulated, and no change when M. luminyensis uses extracellular electron versus H2. MT methylotransferase, MCR methyl-CoM reductase.
