Fumarate hydratase, class II; Involved in the TCA cycle. Catalyzes the stereospecific interconversion of fumarate to L-malate; Belongs to the class-II fumarase/aspartase family. Fumarase subfamily.

ATP citrate lyase, alpha subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme.

Succinyl-CoA synthetase, NAD(P)-binding, alpha subunit; 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 alpha subunit of the enzyme binds the substrates coenzyme A and phosphate, while succinate binding and nucleotide specificity is provided by the beta subunit.

Succinyl-CoA synthetase, beta subunit; 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.

NADH-quinone oxidoreductase, subunits C and D; Function of homologous gene experimentally demonstrated in an other organism; enzyme; In the N-terminal section; belongs to the complex I 30 kDa subunit family.

Succinate dehydrogenase, subunit C; Function of strongly homologous gene; enzyme.

Nicotinate-nucleotide diphosphorylase (carboxylating); Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the NadC/ModD family.

Glycine dehydrogenase, glycine cleavage system P protein; 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.
