WebApr 8, 2024 · Propionyl-CoA carboxylase (PCC) is a multienzyme complex consisting of up to six α-subunits and six β-subunits. Belonging to a metabolic pathway converging on the citric acid cycle, it is present in most forms of life and irregularities in its assembly lead to serious illness in humans, known as propionic acidemia. WebHolocarboxylase synthetase deficiency is an inherited disorder in which the body is unable to use the vitamin biotin effectively. This disorder is classified as a multiple carboxylase deficiency, which is a group of disorders characterized by impaired activity of certain enzymes that depend on biotin.

WebCarboxylation and decarboxylation processes are the main reactions in which biotin is involved. It is linked to the enzymes by an amide bond between the amino group of a specific lysyl residue in the active centre of the respective apocarboxylase and its valeric acid side chain. Pyruvate carboxylase (PC) encoded by the gene PC is an enzyme (EC 6.4.1.1) of the ligase class that catalyzes (depending on the species) the physiologically irreversible carboxylation of pyruvate to form oxaloacetate (OAA). • Pyruvic acid • Oxaloacetic acid how not to overcook chicken
