Aconitate hydratase B; Catalyzes the conversion of citrate to isocitrate and the conversion of 2-methylaconitate to 2-methylisocitrate; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the aconitase/IPM isomerase family.

SucA; E1 component of the oxoglutarate dehydrogenase complex which catalyzes the formation of succinyl-CoA from 2-oxoglutarate; SucA catalyzes the reaction of 2-oxoglutarate with dihydrolipoamide succinyltransferase-lipoate to form dihydrolipoamide succinyltransferase-succinyldihydrolipoate and carbon dioxide; Derived by automated computational analysis using gene prediction method: Protein Homology.

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

Glutamate dehydrogenase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the Glu/Leu/Phe/Val dehydrogenases family.

Isocitrate dehydrogenase; NADP-specific, catalyzes the formation of 2-oxoglutarate from isocitrate or oxalosuccinate; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the monomeric-type IDH family.

Malate dehydrogenase; Catalyzes the reversible oxidation of malate to oxaloacetate. Belongs to the LDH/MDH superfamily. MDH type 2 family.

Bifunctional isocitrate dehydrogenase kinase/phosphatase; Bifunctional enzyme which can phosphorylate or dephosphorylate isocitrate dehydrogenase (IDH) on a specific serine residue. This is a regulatory mechanism which enables bacteria to bypass the Krebs cycle via the glyoxylate shunt in response to the source of carbon. When bacteria are grown on glucose, IDH is fully active and unphosphorylated, but when grown on acetate or ethanol, the activity of IDH declines drastically concomitant with its phosphorylation.

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.

Glycine dehydrogenase (aminomethyl-transferring); 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.
