Metabolite Identification
Common Name 6-Phosphonoglucono-D-lactone
Description 6-phosphoglucono-delta-lactone (d-6PGL) is the immediate product of the Glucose-6-phosphate dehydrogenase (G-6-PD), the first enzyme of the hexose monophosphate pathway. (PMID 3711719 Link_out). The pentose-phosphate pathway provides reductive power and nucleotide precursors to the cell through oxidative and nonoxidative branches. 6-Phosphogluconolactonase is the second enzyme of the oxidative branch and catalyzes the hydrolysis of 6-phosphogluconolactones, the products of glucose 6-phosphate oxidation by glucose-6-phosphate dehydrogenase. By efficiently catalyzing the hydrolysis of d-6PGL, 6-phosphogluconolactonase prevents the reaction between d-6PGL and intracellular nucleophiles; such a reaction would interrupt the functioning of the pentose-phosphate pathway. (PMID 11457850 Link_out).
