EC Number: 18.104.22.1681
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
Mass balance status: Balanced.
Enzyme Commission Primary Name: phosphogluconate dehydrogenase [NAD(P)+-dependent, decarboxylating]
While the official EC reaction includes NADP+ rather than NAD(P)+, the comments state that some preparations reduce NAD+ as well as NADP+, making NAD(P)+ a more accurate depiction.
Enzyme Commission Summary:
The enzyme participates in the oxidative branch of the pentose phosphate pathway, whose main purpose is to produce reducing power and pentose for biosynthetic reactions. Unlike EC 22.214.171.124, phosphogluconate dehydrogenase (NADP+-dependent, decarboxylating), it is not specific for NADP and can accept both cofactors with similar efficiency. cf. EC 126.96.36.1993, phosphogluconate dehydrogenase (NAD+-dependent, decarboxylating).
