The reaction it catalyzes is: pyruvate + HCO − 3 + ATP → oxaloacetate + ADP + P. It is an important anaplerotic reaction that creates oxaloacetate from pyruvate. Pyruvate carboxylase. Pyruvate carboxylase (PC) encoded by the gene PC is an enzyme of the ligase class that catalyzes (depending on the species) the physiologically irreversible[citation needed] carboxylation of pyruvate to form oxaloacetate (OAA). Aside from the role of PC in gluconeogenesis, PC serves an anaplerotic role (an enzyme catalyzed reaction that can replenish the supply of intermediates in the citric acid cycle) for the tricarboxylic acid cycle (essential to provide oxaloacetate), when intermediates are removed for different biosynthetic purposes. Pyruvate carboxylase enzyme is located in the mitochondrial matrix and it participates in the carboxylation of pyruvate into oxaloacetate. Purification and properties of the apoenzyme and the holoenzyme synthetase. Insights into the mechanism and regulation of pyruvate carboxylase by characterisation of a biotin-deficient mutant of the Bacillus thermodenitrificans enzyme. Organism. Under ordinary gluconeogenic conditions, OAA is converted into PEP by mitochondrial PEPCK; the resultant PEP is then transported out of the mitochondrial matrix by an anion transporter carrier system,[14] and converted into glucose by cytosolic gluconeogenic enzymes.

Pyruvate carboxylase (PC) catalyzes the biotin-dependent carboxylation of pyruvate to produce oxaloacetate. Bioprocess Engineering 1995, 12 (3) , 157-162. Formally, pyruvate is first converted to oxaloacetate, which is in turn converted to PEP. As a crossroad between carbohydrate and lipid metabolism, pyruvate carboxylase expression in gluconeogenic tissues, adipose tissues and pancreatic islets must be coordinated. This is a very important anaplerotic reaction, replenishing oxaloacetate withdrawn from the tricarboxylic acid cycle for various pivotal biochemical pathways. Four single-site mutations, V145A, R451C, A610T, M743I, are associated with these diseases.

The quaternary structures of the pyruvate carboxylases studied so far, all involve a tetrahedron-like arrangement of the subunits. [12][13] The major regulator of enzyme activity, acetyl-CoA, stimulates the cleavage of ATP in the first partial reaction and also it has been shown to induce a conformational change in the tetrameric structure of the enzyme. The domain structure of the yeast enzyme has been deduced by comparing its amino acid sequence with those of enzymes that have similar catalytic functions. doi: 10.1128/AEM.01972-20. [17][18] Similarly to other gluconeogenic enzymes, PC is positively regulated by glucagon and glucocorticoids while negatively regulated by insulin. [30] Normally, excess pyruvate is shunted into gluconeogenesis via conversion of pyruvate into oxaloacetate, but because of the enzyme deficiency, excess pyruvate is converted into lactate instead. PC has crucial roles in gluconeogenesis, lipogenesis, glyceroneogenesis, and insulin secretion in mammals. This is a very important anaplerotic … Subcell Biochem. It catalyses the carboxylation of pyruvate to oxaloacetate using bicarbonate and coupled to the … In type 2 diabetic rats, chronic exposure of β-cells to glucose due to peripheral insulin resistance results in decreased PC enzyme activity and decreased pyruvate cycling[23][24] The continued overproduction of glucose by hepatocytes causes dramatic alteration of gene expression in β-cells with large increases in normally suppressed genes, and equivalent decreases in expression of mRNA for insulin, ion pumps necessary for insulin secretion, and metabolic enzymes related to insulin secretion, including pyruvate carboxylase[25][26] Concurrently adipose tissue develops insulin resistance causing accumulation of triaglycerols and non-esterified fatty acids in circulation; these not only further impairing β-cell function,[26][27] but also further decreasing PC expression. The carboxyl group is subsequently transferred by carboxybiotin to a second active site in the CT domain, where pyruvate is carboxylated to generate oxaloacetate. ZY‐444 binds to cellular pyruvate carboxylase (PC), a key anaplerotic enzyme of the tricarboxylic acid cycle, and inactivates its catalytic activity.  |  The reaction proceeds via the removal of a proton from pyruvate, by an as yet unidentified active site residue, to generate an enolate intermediate.
