Protein
Purine nucleoside phosphorylase
Gene
punA
Organism
Cellulomonas sp.
Status
Reviewed - Annotation score: 3 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. Cleaves guanosine and inosine.1 Publication

Catalytic activityi

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