Part of four member fumarate reductase enzyme complex FrdABCD which catalyzes the reduction of fumarate to succinate during anaerobic respiration; FrdAB are the catalytic subcomplex consisting of a flavoprotein subunit and an iron-sulfur subunit, respectively; FrdCD are the membrane components which interact with quinone and are involved in electron transfer; the catalytic subunits are similar to succinate dehydrogenase SdhAB; Derived by automated computational analysis using gene prediction method: Protein Homology.

Part of four member succinate dehydrogenase enzyme complex that forms a trimeric complex (trimer of tetramers); SdhA/B are the catalytic subcomplex and can exhibit succinate dehydrogenase activity in the absence of SdhC/D which are the membrane components and form cytochrome b556; SdhC binds ubiquinone; oxidizes succinate to fumarate while reducing ubiquinone to ubiquinol; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.

Formate dehydrogenase; Selenocysteine-containing polypeptide; hydrogen linked formate dehydrogenase which catalyzes the oxidation of formate; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.

Electron transfer protein for hydrogenase-3; the formate hydrogenlyase complex comprises of a formate dehydrogenase, unidentified electron carriers and hydrogenase-3; in this non-energy conserving pathway, molecular hydrogen and carbodioxide are released from formate; Derived by automated computational analysis using gene prediction method: Protein Homology.

NADH dehydrogenase; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient.

Ferredoxin; Derived by automated computational analysis using gene prediction method: Protein Homology.

Malate dehydrogenase; Catalyzes the reversible oxidation of malate to oxaloacetate.

Succinate dehydrogenase; Derived by automated computational analysis using gene prediction method: Protein Homology.

Protein acetyltransferase; Catalyzes the acetylation of lysine; Derived by automated computational analysis using gene prediction method: Protein Homology.
