Protein
Hypoxanthine-guanine phosphoribosyltransferase
Organism
Trypanosoma brucei brucei
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 (By similarity).
Similarity
Belongs to the purine/pyrimidine phosphoribosyltransferase family.
