The biosynthesis of phosphoribosyl pyrophosphate begins as a product of the pentose phosphate and D-ribose 5-phosphate interaction. When catalyzed with a phosphopentomutase, the product is a ribose 1-phosphate. Ribose 1-phosphate can interact spontaneously with ATP resulting in a release of hydrogen ion, ADP and a ribose 1,5-biphosphate. Ribose 1,5-biphosphate is then phosphorylated through a ribose 1,5-bisphosphokinase resulting in the release of ADP and phosphoribosyl pyrophosphate. Phosphoribosyl pyrophosphate will then participate in the purine nucleotides de novo biosynthesis pathway. Alternatively pentose phosphate and D-ribose 5-phosphate's interaction can be phosphorylated through an ATP driven ribose-phosphate diphosphokinase resulting in a release of a hydrogen ion, an AMP and a phosphoribosyl pyrophosphate which will again participate in the purine nucleotides de novo biosynthesis pathway.
