WebThe late steps of biotin synthesis, those involved in assembling the fused rings, were well described biochemically years ago, although recent progress has been made on the BioB reaction, the last step of the pathway, in which the biotin sulfur moiety is inserted. In contrast, the early steps of biotin synthesis, assembly of the fatty acid-like ... 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 ...
