Enzyme Information

1.1.1.44

Phosphogluconate dehydrogenase (NADP(+)-dependent, decarboxylating).

based on mapping to UniProt P31072

6-phospho-D-gluconate + NADP(+) = D-ribulose 5-phosphate + CO(2) + NADPH.

-!- 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.
