Common NameD-Tagaturonate
DescriptionD-Tagaturonate is a sugar acid belonging to the class of carbohydrates, specifically a uronate. Its chemical structure features a six-carbon backbone with a carboxyl group, making it a key intermediate in various metabolic pathways. D-Tagaturonate is involved in the conversion of D-fructose to D-tagatose through the action of D-tagaturonate 3-epimerases, which facilitate C-4 epimerization (PMID:40690603 ). Additionally, it plays a role in the enzymatic transformation of D-fructuronate to D-tagaturonate mediated by UxaE, linking distinct metabolic pathways (PMID:32758598 ). The biosynthesis of D-tagaturonate from L-galactose involves a series of previously uncharacterized enzymes, with Bvu0222 catalyzing the oxidation of L-galactonate to D-tagaturonate (PMID:24963813 ). In the degradation pathway, D-tagaturonate is further metabolized to D-glyceraldehyde and pyruvate (PMID:24963813 ). Furthermore, D-tagaturonate is epimerized from 5-keto-L-gluconate by the enzyme TM0416 (IolO) (PMID:23441918 ), and its reduction is facilitated by D-tagaturonate reductase in bacterial D-galacturonate pathways (PMID:23079077 ). Overall, D-tagaturonate serves as a crucial metabolite in carbohydrate metabolism.
