IntEnz Enzyme Nomenclature
EC 1.1.1.44

Names

Accepted name:
phosphogluconate dehydrogenase (NADP+-dependent, decarboxylating)
Other names:
6-phospho-D-gluconate dehydrogenase
6-phosphogluconate dehydrogenase (decarboxylating)
6-phosphogluconic carboxylase
6-phosphogluconic dehydrogenase
phosphogluconic acid dehydrogenase
6PGD
Systematic name:
6-phospho-D-gluconate:NADP+ 2-oxidoreductase (decarboxylating)

Reaction

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 1.1.1.343, phosphogluconate dehydrogenase (NAD+-dependent, decarboxylating).
