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.

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

Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the citrate synthase family.

Citrate synthase; Catalyzes the formation of citrate from acetyl-CoA and oxaloacetate; Derived by automated computational analysis using gene prediction method: Protein Homology.

Glycine dehydrogenase; The glycine cleavage system catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO(2) is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein; Belongs to the GcvP family.

2-oxoisovalerate dehydrogenase; Derived by automated computational analysis using gene prediction method: Protein Homology.

2-oxoisovalerate 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.
