5-Phospho-D-ribose 1-diphosphate (PRPP) is a natural intermediate involved in the pentose phosphate pathway leading to purine, pyrimidine, and histidine metabolism. It is also an intermediate in the synthesis of plant hormones, alkaloids, and other secondary metabolites from glucose. Several phosphoribosyltransferases (PRTases) use PRPP as a substrate to add a 5-phosphoribosyl group to another substrate, as in the production of adenosine monophosphate from adenine and PRPP by adenine PRTase.
