Standard Name	PRS2 1 (see Nomenclature conflict Note)
Systematic Name	YER099C
Feature Type	ORF, Verified
Description	5-phospho-ribosyl-1(alpha)-pyrophosphate synthetase, synthesizes PRPP, which is required for nucleotide, histidine, and tryptophan biosynthesis; one of five related enzymes, which are active as heteromultimeric complexes; PRS2 has a paralog, PRS4, that arose from the whole genome duplication (1, 2, 3)
Name Description	PhosphoRibosylpyrophosphate Synthetase 4

Chromosomal Location	ChrV:359061 to 358105 | ORF Map | GBrowse
