Ribose-phosphate diphosphokinase (or phosphoribosyl pyrophosphate synthetase or ribose-phosphate pyrophosphokinase) is an enzyme that converts ribose 5-phosphate into phosphoribosyl pyrophosphate (PRPP). [1] [2] It is classified under EC 2.7.6.1.

Phosphoribosyl pyrophosphate (PRPP) is a pentose phosphate. It is a biochemical intermediate in the formation of purine nucleotides via inosine-5-monophosphate, as well as in pyrimidine nucleotide formation. Hence it is a building block for DNA and RNA.
R5P converts to PRPP, which forces an overproduction of purines, leading to uric acid build up. [8] Accumulation of PRPP is found in Lesch-Nyhan Syndrome. [16] The build up is caused by a deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase (HGPRT), which leads to decreased nucleotide synthesis and an increase of uric acid ...
The formation of 5'-phosphoribosylamine from glutamine and PRPP catalysed by PRPP amino transferase is the regulation point for purine synthesis. The enzyme is an allosteric enzyme, so it can be converted from IMP, GMP and AMP in high concentration binds the enzyme to exerts inhibition while PRPP is in large amount binds to the enzyme which ...
Orotic acid and PRPP are stabilized in the active site mostly by hydrogen bonding with stabilizing interactions from Lys 26, Phe 34 and Phe 35 to orotic acid, as well as Thr 128, Ala 129, Gly 130, Ala 132, Asp 124, Lys 26 and Lys 73 to PRPP. [14] When Lys 26 is mutated, orotate phosphoribosyltransferase often exhibits reduced activity and ...
