Anwendung
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. Wirkung
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.
Einheitendefinition
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

Several acyclic hydroxy-methylthio-amines with 3-5 carbon atoms were prepared and coupled via a methylene link to 9-deazaadenine. The products were tested for inhibition against human MTAP and Escherichia coli and Neisseria meningitidis MTANs and gave K(i) values as low as

Combination therapy with the ribavirin (RBV) prodrug taribavirin (TBV) and pegylated interferon (PIFN) has produced lower rates of anaemia than with RBV and PIFN. Studies have demonstrated that the sharpest decline in viral load during TBV therapy occurs at Weeks
