Chains	Enzyme Name	Description	Catalytic Residues
A	hypoxanthine phosphoribosyltransferase M-CSA #48	Converts guanine to guanosine monophosphate, and hypoxanthine to inosine monophosphate. Transfers the 5-phosphoribosyl group from 5-phosphoribosylpyrophosphate onto the purine. Plays a central role in the generation of purine nucleotides through the purine salvage pathway and is involved in the first step of the subpathway that synthesizes IMP from hypoxanthine.
