Pyridoxine-5′-phosphate oxidase is an enzyme that in humans is encoded by the PNPO gene.Vitamin B6 or pyridoxal 5-prime-phosphate (PLP) is critical for normal cellular function and some cancer cells have notable differences in vitamin B6 metabolism compared to their normal counterparts. The rate-limiting enzyme in vitamin B6 synthesis is pyridoxine-5-prime-phosphate (PNP) oxidase (PNPO; EC 1.4.3.5).[supplied by OMIM]
