In enzymology, a biotin carboxylase (EC 6.3.4.14) is an enzyme that catalyzes the chemical reaction ATP + biotin-carboxyl-carrier protein + CO2 $${\displaystyle \rightleftharpoons }$$ ADP + phosphate + carboxybiotin-carboxyl-carrier protein The three substrates of this enzyme are ATP, biotin-carboxyl-carrier … See more Biotin carboxylases are a conserved enzyme present within biotin-dependent carboxylase complexes such as acetyl-CoA carboxylase. How biotin carboxylase functions is, within the relevant carboxylase … See more As of late 2007 , 5 structures have been solved for this class of enzymes, with PDB accession codes 1BNC, 1DV1, 1DV2, 2GPS, and 2GPW. The crystal structure has been determined for the biotin carboxylase (acetyl-CoA carboxylase) of … See more • Dimroth P, Guchhait RB, Stoll E, Lane MD (1970). "Enzymatic carboxylation of biotin: molecular and catalytic properties of a component enzyme of acetyl CoA carboxylase" See more WebTarget Information. Acetyl-CoA carboxylase (ACC) is a complex multifunctional enzyme system. ACC is a biotin-containing enzyme which catalyzes the carboxylation of acetyl-CoA to malonyl-CoA, the rate-limiting step in fatty acid synthesis.

WebIn humans, biotin is involved in important metabolic pathways such as gluconeogenesis, fatty acid synthesis, and amino acid catabolism by acting a as prosthetic group for pyruvate carboxylase, propionyl-CoA carboxylase, beta-methylcrotinyl-CoA carboxylase, and acetyl-CoA carboxylase. Webvolved in biotin-binding or biotin-mediated stabiliz-ation of the protein. INTRODUCTION Holocarboxylase synthetase (HCS; EC 6.3.4.10) catalyzes the biotinylation of the four biotin-dependent carboxylases found in humans: the mitochondrial propionyl-CoA carboxylase (PCC), pyruvate carboxylase (PC) and β-methylcrotonyl-CoA orange county public school list
Biotinidase Deficiency Article - StatPearls
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.
