Name Hypoxanthine-guanine phosphoribosyltransferase
Description Not Available
Synonyms
  1. HGPRT
  2. HGPRTase
Gene Name HPRT1
Protein Type Enzyme
Biological Properties
General Function Involved in hypoxanthine phosphoribosyltransferase activity
Specific Function 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.
