Biotin Synthase - an overview ScienceDirect Topics
WebBiotin synthase catalyzes formation of a thiophane ring through a radical mechanism that is difficult to reconstitute in vitro. Choi-Rhee and Cronan measure a turnover of 20-60 equivalents of biotin in vivo, but also find that turnover renders the protein susceptible to proteolytic destruction. WebJul 23, 2002 · Biotin synthase (BioB) is an iron-sulfur dimeric enzyme which catalyzes the last step in biotin synthesis. The reaction consists of the introduction of a sulfur atom into dethiobiotin. It is shown here that BioB displays a significant cysteine desulfurase activity, providing it with the ability to m … WebBiotin 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 ... python tsp问题
