Function

The enzyme phosphoribosyl pyrophosphate synthetase (PRS) catalyzes the formation of phosphoribosyl pyrophosphate which is a substrate for synthesis of purine and pyrimidine nucleotides, histidine, tryptophan and NAD. PRS exists as a complex with two catalytic subunits and two associated subunits. This gene encodes a non-catalytic associated subunit of PRS.^[5]
