Biotin sulfoxidePurinosomeStreptavidin: Streptavidin is a 52.8 kDa protein purified from the bacterium Streptomyces avidinii.Propionyl-CoA carboxylase: Propionyl-CoA carboxylase catalyses the carboxylation reaction of propionyl CoA in the mitochondrial matrix. The enzyme is biotin-dependent.Pyruvate carboxylaseMolybdopterin synthase sulfurtransferase: Molybdopterin synthase sulfurtransferase (, adenylyltransferase and sulfurtransferase MOCS3, Cnx5 (gene), molybdopterin synthase sulfurylase) is an enzyme with system name persulfurated L-cysteine desulfurase:(molybdopterin-synthase sulfur-carrier protein)-Gly-Gly sulfurtransferase. This enzyme catalyses the following chemical reactionCalcium beta-hydroxy-beta-methylbutyrateBiotinidase: Biotinidase , amidohydrolase biotinidase, BTD) is an enzyme that in humans is encoded by the BTD gene.Gamma-glutamyl carboxylase: Gamma-glutamyl carboxylase is an enzyme that in humans is encoded by the GGCX gene, located on chromosome 2 at 2p12.ACACB: Acetyl-CoA carboxylase 2 also known as ACC-beta or ACC2 is an enzyme that in humans is encoded by the ACACB gene.Malonyl-S-ACP:biotin-protein carboxyltransferase: Malonyl-S-ACP:biotin-protein carboxyltransferase (, malonyl-S-acyl-carrier protein:biotin-protein carboxyltransferase, MadC/MadD, MadC,D, malonyl-[acyl-carrier protein]:biotinyl-[protein] carboxyltransferase) is an enzyme with system name malonyl-(acyl-carrier protein):biotinyl-(protein) carboxytransferase. This enzyme catalyses the following chemical reactionPimelic acidHoof boot: A hoof boot is a device made primarily of polyurethane and is designed to cover the hooves of a horse as an alternative to, and occasionally in addition to, horseshoes. Hoof boots can also be used as a protective device when the animal has a hoof injury that requires protection of the sole of the hoof, or to aid in the application of medication.Multiple carboxylase deficiency: Multiple carboxylase deficiency is a form of metabolic disorder involving failures of carboxylation enzymes.Egg white: Egg white is the common name for the clear liquid (also called the albumen or the glair/glaire) contained within an egg. In chickens it is formed from the layers of secretions of the anterior section of the hen's oviduct during the passage of the egg.Cubam: Cubam, is the term used to refer to a multi-ligand receptor located in the terminal ileum, specializing in absorption of vitamin B12. Cubam is essentially composed of amnionless (AMN), and cubilin.Group IV pyridoxal-dependent decarboxylases: In molecular biology, group IV pyridoxal-dependent decarboxylases are a family of enzymes comprising ornithine decarboxylase , lysine decarboxylase , arginine decarboxylase and diaminopimelate decarboxylase. It is also known as the Orn/Lys/Arg decarboxylase class-II family.List of strains of Escherichia coli: Escherichia coli is a well studied bacterium that was first identified by Theodor Escherich, after whom it was later named.Pantothenic acidHolocarboxylase synthetase deficiency: Holocarboxylase synthetase deficiency is an inherited metabolic disorder in which the body is unable to use the vitamin biotin effectively. This disorder is classified as a multiple carboxylase deficiency, a group of disorders characterized by impaired activity of certain enzymes that depend on biotin.
