Biotin synthese
WebAbstract. Biotin synthase (BioB) catalyzes the oxidative insertion of a sulfur atom between the C6 methylene and the C9 methyl positions in dethiobiotin. The enzyme couples oxidation of each carbon position to reduction of the S -adenosyl- l -methionine (SAM) sulfonium center, generating 5′-deoxyadenosine and l -methionine, products that are ... 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 …
