Metabolite Identification
Common NameD-erythronate
DescriptionD-erythronate is a four-carbon sugar alcohol belonging to the class of metabolites known as sugar acids. Its chemical structure features a hydroxyl group on each of the four carbon atoms, making it a diastereomer of D-threonate. D-erythronate is primarily involved in catabolic pathways, particularly in the metabolism of N-acetyl-d-glucosamine, a nutritional supplement linked to joint health (PMID:38157628 ). The catabolic pathways for D-erythronate have been characterized in various bacterial species, notably within the phyla Actinomycetota, Cyanobacteriota, Bacillota, Pseudomonadota, and Bacteroidota (PMID:38157628 ). In Brucella, a virulence-related DeoR-family transcriptional regulator (VdtR) has been identified that negatively regulates the erythronate metabolic pathway, promoting the bacterium's extracellular proliferation by utilizing D-erythronate, an oxidative product of erythritol (PMID:37671873 ). Furthermore, studies indicate that D-erythronate and other acid sugars share similar enzymatic catalysis and catabolic pathways, highlighting its relevance in microbial metabolism (PMID:30316512 ). Despite its significance, the detailed catabolism of D-erythronate remains sparsely reported in the literature (PMID:38157628 ).
