Metabolite Identification
Common Name5-Keto-D-gluconate
Description5-Keto-D-gluconate is metabolized from glucose in certain bacterial species. It is an intermediate in L-idonate degradation and ketogluconate metabolism. 5-Keto-D-gluconate 5-reductase catalyzes the reversible reduction of 5-ketogluconate to D-gluconate. This is the second reaction of the L-idonate catabolic pathway after uptake of L-idonate into the cell. The enzyme specifically reduces 5-ketogluconate using either NADH or NADPH. The enzyme is also specific for D-gluconate oxidation using NADP as the coenzyme, NAD does not serve as a coenzyme. 5-Keto-D-gluconate has also been found to be a metabolite of Gluconobacter (https://www.sciencedirect.com/science/article/pii/S138111779800112X).
