Protein

Purine nucleoside phosphorylase

Gene

Pnp

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

The purine nucleoside phosphorylases catalyze 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.By similarity

Catalytic activityi

Purine nucleoside + phosphate = purine + alpha-D-ribose 1-phosphate.By similarity
