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

Type II enzyme; in Escherichia coli this enzyme forms a trimer of dimers which is allosterically inhibited by NADH and competitively inhibited by alpha-ketoglutarate; allosteric inhibition is lost when Cys206 is chemically modified which also affects hexamer formation; forms oxaloacetate and acetyl-CoA and water from citrate and coenzyme A; functions in TCA cycle, glyoxylate cycle and respiration; enzyme from Helicobacter pylori is not inhibited by NADH; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the citrate synthase family.

acetyl-CoA carboxylase biotin carboxylase subunit; This protein is a component of the acetyl coenzyme A carboxylase complex; first, biotin carboxylase catalyzes the carboxylation of the carrier protein and then the transcarboxylase transfers the carboxyl group to form malonyl-CoA.

acetyl-CoA carboxylase subunit beta; Component of the acetyl coenzyme A carboxylase (ACC) complex. Biotin carboxylase (BC) catalyzes the carboxylation of biotin on its carrier protein (BCCP) and then the CO(2) group is transferred by the transcarboxylase to acetyl-CoA to form malonyl-CoA; Belongs to the AccD/PCCB family.

Pyruvate carboxylase subunit B; Catalyzes the formation of oxaloacetate from pyruvate; Derived by automated computational analysis using gene prediction method: Protein Homology.

succinate--CoA ligase 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.

succinate--CoA ligase subunit alpha; 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.

Pyruvate carboxylase subunit A; Catalyzes the ATP-dependent carboxylation of a covalently attached biotin and the transfer of the carboxyl group to pyruvate forming oxaloacetate; Derived by automated computational analysis using gene prediction method: Protein Homology.

Pyruvate dehydrogenase; Component of the pyruvate dehydrogenase (PDH) complex, that catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2).
