Opis

Application

Nucleoside Phosphorylase bacterial has been used in reaction buffer and buffer-exchanged to remove residual phosphate.

Bacterial nucleoside phosphorylase has been used in a study that identified and characterized two adenosine phosphorylase activities in Mycobacterium smegmatis. Bacterial nucleoside phosphorylase has also been used in a study to investigate the inhibitionof pyrimidine and purine nucleoside phosphorylases by a 3,5-dichlorobenzoyl-substituted 2-deoxy-D-ribose-1-phosphate derivative.

Nucleoside phosphorylase is used in coupled enzyme systems to measure protein dephosphorylation.

Biochem/physiol Actions

Nucleoside Phosphorylase/purine nucleoside phosphorylase (PNP), an enzyme participates in the purine salvage pathway. It also helps in the reversible cleavage of inosine to hypoxanthine and guanosine to guanine. PNP deficiency results in neurologic manifestations.

Catalyzes the following reaction:purine nucleoside + phosphate = purine + alpha-D-ribose 1-phosphate

Preparation Note

This is a salt-free and animal component-free enzyme preparation. This enzyme should be solubilized in a 10mM KPO₄, pH 7.4 solution.

Other Notes

One unit will cause the phosphorolysis of 1.0 micromole of inosine to hypoxanthine andribose-1-phosphate per min at pH 7.4 at 25 deg C.
