Protein Name: Purine nucleoside phosphorylase

UniprotKB/SwissProt ID: P23492 (P23492)

Gene Name: Pnp

Organism: Mus musculus (Mouse)

Function: Catalyzes the phosphorolytic breakdown of the N-glycosidic bond in the beta-(deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate (Probable) (PubMed:10859343). Preferentially acts on 6-oxopurine nucleosides including inosine and guanosine (Probable)

Other Modifications: View all modification sites in dbPTM
