Metabolite Identification
Common Name2-deoxy-5-keto-D-gluconic acid
Description2-deoxy-5-keto-D-gluconic acid is a carbohydrate metabolite belonging to the class of keto sugars. This compound plays a crucial role in various biochemical pathways, particularly in the metabolism of carbohydrates. It is generated through the isomerization of 5-deoxy-D-glucuronic acid by the enzyme IolB (PMID:18310071 ). Subsequently, 2-deoxy-5-keto-D-gluconic acid is phosphorylated by IolC kinase to form 2-deoxy-5-keto-D-gluconic acid 6-phosphate, which serves as an important intermediate in metabolic processes (PMID:18310071 ). This phosphorylated form acts as an inducer by antagonizing the DNA binding of IolR (PMID:18310071 ). Additionally, the compound is involved in the conversion to glycolytic intermediates, highlighting its significance in energy metabolism (PMID:4328832 ). The final step in its metabolic pathway involves the cleavage of 2-deoxy-5-keto-D-gluconic acid 6-phosphate by the aldolase IolJ, yielding dihydroxyacetone phosphate and malonic semialdehyde (PMID:18310071 ). Overall, 2-deoxy-5-keto-D-gluconic acid is a pivotal intermediate in carbohydrate metabolism, facilitating the transition between different metabolic states.
