Webphosphopentose isomerase. Under many metabolic conditions the phosphogluconate pathway ends at this point. The net result is the production of NADPH for reductive synthesis and the production of D-ribose-5-phosphate for nucleotide synthesis. However, many cells need more NADPH than ribose-5-phosphate or they may not need ribose-5-phosphate at all.
