Application
Purine nucleoside phosphorylase is used to study nucleotide salvage pathways and purine metabolism. It is used to study purine nucleoside phosphorylase deficiency and responsible PNP genetic mutations.
Biochem/physiol Actions
Purine nucleoside phosphorylase is an enzyme involved in purine metabolism. PNP metabolizes adenosine into adenine, inosine into hypoxanthine, and guanosine into guanine. Mutations in the PNP gene are responsible for purine nucleoside phosphorylase deficiency.
Other Notes
1 U will cause the phosphorolysis 1 μmol of inosine to hypoxanthine and ribose 1-phosphate per minute at pH 7.4 at 25°C

Human purine nucleoside phosphorylase (PNP) is a ubiquitous enzyme which plays a key role in the purine salvage pathway, and PNP deficiency in humans leads to an impairment of T-cell function, usually with no apparent effect on B-cell function. PNP

Nucleoside phosphorylases are essential for the salvage and catabolism of nucleotides in bacteria and other organisms, and members of this enzyme superfamily have been of interest for the development of antimicrobial and cancer therapies. The nucleotide phosphorylase superfamily 1 encompasses
