Application


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


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.


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


Packaging


100, 250, 1000 units in poly bottle


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.


Unit Definition


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.
