Function
function
Catalyzes a salvage reaction resulting in the formation of IMP that is energically less costly than de novo synthesis.
Catalytic activity
- diphosphate + IMP = 5-phospho-alpha-D-ribose 1-diphosphate + hypoxanthine
Pathway
Purine metabolism; IMP biosynthesis via salvage pathway; IMP from hypoxanthine: step 1/1.
