DescriptionDethiobiotin is an intermediate in biotin biosynthesis from 7-keto-8-aminopelargonate pathway. Biotin is a water soluble, heterocyclic cofactor for a small number of enzymes that facilitate the transfer of CO2 during carboxylation, decarboxylation, and transcarboxylation reactions involved in fatty acid and carbohydrate metabolism. Biotin biosynthesis is found in plants, bacteria, and certain fungi. [Biocyc PWY0-1507]
