General annotation (Comments)
| Function | Catalyzes the rate-limiting step of the oxidative pentose-phosphate pathway, which represents a route for the dissimilation of carbohydrates besides glycolysis. The main function of this enzyme is to provide reducing power (NADPH) and pentose phosphates for fatty acid and nucleic acid synthesis which are involved in membrane synthesis and cell division. |
| Catalytic activity | D-glucose 6-phosphate + NADP+ = 6-phospho-D-glucono-1,5-lactone + NADPH. |
| Enzyme regulation | Regulated by metabolites. Post-translationally inactivated by cysteine-mediated redox modification via the ferredoxin-thioredoxin system in the light and this avoids futile cycles with photosynthetic CO2 fixation By similarity. |
| Pathway | |
| Subunit structure | Homodimer By similarity. |
| Subcellular location | Plastid › chloroplast By similarity. |
| Miscellaneous | There are 6 glucose-6-phosphate 1-dehydrogenase genes in A.thaliana. |
| Sequence similarities | Belongs to the glucose-6-phosphate dehydrogenase family. |
