    Biotin is the vitamin essential for many biological carboxylation reactions, such as the conversion of acetyl-coenzyme A (CoA) to malonyl-CoA in fatty acid biosynthesis. Dethiobiotin synthetase (DTBS) facilitates the penultimate, ureido ring closure in biotin synthesis, which is a non-biotin-dependent carboxylation. DTBS displays no sequence similarity to any other protein in the database. Structural studies provide a molecular insight into the reaction mechanism of DTBS.
