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
