Function
function
Catalyzes the reversible 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.
Catalytic activity
- a purine 2'-deoxy-D-ribonucleoside + phosphate = a purine nucleobase + 2-deoxy-alpha-D-ribose 1-phosphate
