Model of the bioenergetics and biochemistry of acetogenesis from formate in T. kivui. HDCR, hydrogen-dependent CO2 reductase; HydABC, electron-bifurcating hydrogenase; CODH/ACS, CO dehydrogenase/acetyl-CoA synthase; THF, tetrahydrofolate; HCO-THF, formyl-THF; HC-THF, methenyl-THF; H2C-THF, methylene-THF; H3C-THF, methyl-THF; Ech, energy-converting hydrogenase; Ech-MetFV, energy-converting hydrogenase complex coupled to methylene-THF reductase; CoFeSP, corrinoid-iron-sulfur-protein; Fd2−, reduced ferredoxin. The Ech-MetFV complex is hypothetical. The ion stoichiometries for the membrane proteins have not been determined experimentally.
