WebMar 13, 2024 · Biotin serves as a cofactor for four carboxylases: 3-methylcrotonyl carboxylase, propionyl-CoA carboxylase, acetyl-CoA carboxylase and pyruvate carboxylase. Holocarboxylase synthetase catalyzyes the covalent addition of biotin to the four carboxylases, thereby activating the enzymes. WebBiotin, also known as vitamin B 7 or vitamin H, is an essential vitamin because it acts as a cofactor for five biotin-dependent carboxylases that play critical roles in the intermediate metabolism of gluconeogenesis, fatty acid synthesis, and amino acid catabolism. 1 Pharmacology and pathophysiology of biotin have been discussed in Chapter 2.The …
WebAug 24, 2007 · The enzyme uses a covalently attached biotin cofactor to catalyze the adenosine triphosphate (ATP)–dependent carboxylation of pyruvate to oxaloacetate in two steps ( 10 ). Biotin is initially carboxylated at the BC active site by ATP and bicarbonate. The carboxyl group is subsequently transferred by carboxybiotin to a second active site in ... WebBiotin plays an essential role in growth of mycobacteria.
