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.

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

Catalyzes the fumarate and succinate interconversion; fumarate reductase is used under anaerobic conditions with glucose or glycerol as carbon source; Derived by automated computational analysis using gene prediction method: Protein Homology.

Succinate dehydrogenase; 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.

succinyl-CoA synthetase subunit beta; Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The beta subunit provides nucleotide specificity of the enzyme and binds the substrate succinate, while the binding sites for coenzyme A and phosphate are found in the alpha subunit.

Fumarate hydratase; Catalyzes the reversible hydration of fumarate to (S)-malate. Belongs to the class-I fumarase family.

Nicotinate-nucleotide pyrophosphorylase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the NadC/ModD family.
