Other name(s): phosphogluconic acid dehydrogenase; 6-phosphogluconic dehydrogenase; 6-phosphogluconic carboxylase; 6-phosphogluconate dehydrogenase (decarboxylating); 6-phospho-D-gluconate dehydrogenase
Systematic name: 6-phospho-D-gluconate:NADP+ 2-oxidoreductase (decarboxylating)
Comments: The enzyme participates in the oxidative branch of the pentose phosphate pathway, whose main purpose is to produce NADPH and pentose for biosynthetic reactions. Highly specific for NADP+. cf. EC 18.104.22.1683, phosphogluconate dehydrogenase (NAD+-dependent, decarboxylating).
