Protein

Purine nucleoside phosphorylase

Gene

Pnp

Organism
Mus musculus (Mouse)
Status
Unreviewed-Annotation score: -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.UniRule annotation

Catalytic activityi

Purine nucleoside + phosphate = purine + alpha-D-ribose 1-phosphate.UniRule annotation

Pathwayi: purine nucleoside salvage

This protein is involved in the pathway purine nucleoside salvage, which is part of Purine metabolism.UniRule annotation
View all proteins of this organism that are known to be involved in the pathway purine nucleoside salvage and in Purine metabolism.
