The purine nucleoside phosphorylase N04 is of bacterial origin and thermostable up to 60°C. Purine nucleoside phosphorylases catalyze the reversible phosphorolytic breakdown of the N-glycosidic bond of (deoxy)ribonucleosides, with the formation of the corresponding free purine base and pentose-1-phosphate.
PNP, PNPase, Pu-NPase, PUNP, NP, adenosine phosphorylase, inosine-guanosine phosphorylase, purine-nucleoside:phosphate ribosyltransferase
(1) purine ribonucleoside + phosphate = purine + α-D-ribose 1-phosphate
(2) purine 2'-deoxyribonucleoside + phosphate = purine + 2-deoxy-α-D-ribose 1-phosphate
