The Characterization of the Purine Nucleoside Phosphorylase from Agaricus bisporus and Its Potential Application in Reducing Purine Content in Beer [PDF]

open access: yesJournal of Fungi
Beer, the most popular alcoholic beverage, poses health risks for individuals with gout and hyperuricemia due to its high purine content. Herein, we identified a novel purine nucleoside phosphorylase (AbPNP) from the edible mushroom Agaricus bisporus and

Radical Dehalogenation and Purine Nucleoside Phosphorylase E. coli: How Does an Admixture of 2′,3′-Anhydroinosine Hinder 2-fluoro-cordycepin Synthesis [PDF]

open access: yesBiomolecules, 2021
During the preparative synthesis of 2-fluorocordycepin from 2-fluoroadenosine and 3′-deoxyinosine catalyzed by E. coli purine nucleoside phosphorylase, a slowdown of the reaction and decrease of yield down to 5% were encountered.

Multistep loss of catalytic and ligand binding abilities of hexameric purine nucleoside phosphorylase [PDF]

open access: yesScientific Reports
It is commonly believed that enzymatic catalysis is such a complex process, that even a small change in any physicochemical property of the enzyme results in a complete loss of the catalytic and ligand-binding capacity of the molecule.

Immunodeficiency, motor delay, and hypouricemia caused by a novel mutation of purine nucleoside phosphorylase gene in an Indian infant [PDF]

open access: yesAnnals of Indian Academy of Neurology, 2019
We describe an 11-month-old boy who presented with recurrent respiratory infections from 6 months of age. His elder sister died at 10 months with severe septicemia and meningitis. The boy had a mild motor delay.

Cloning and expression of recombinant purine nucleoside phosphorylase in the methylotrophic yeast Pichia pastoris

open access: yesJournal of Advanced Biotechnology and Experimental Therapeutics, 2023
Purine Nucleoside Phosphorylase (PNP) is an enzyme involved in biosynthetic pathway of purine nucleosides. Purine nucleoside phosphorylase catalyzes the cleavage of the glycosidic bond of ribo- or deoxyribonucleosides to form the purine base and ...

Investigating the Vital Role of the Identified Abietic Acid from Helianthus annuus L. Calathide Extract against Hyperuricemia via Human Embryonic Kidney 293T Cell Model

open access: yesMolecules, 2023
To explore the anti-hyperuricemia components in sunflower (Helianthus annuus L.) calathide extract (SCE), we identified abietic acid (AA) via liquid chromatography–mass spectrometry and found an excellent inhibitor of xanthine oxidase (IC50 = 10.60 µM ...

Purine nucleoside phosphorylase [PDF]

open access: yesBiomeditsinskaya Khimiya, 2013
Purine nucleoside phosphorylase (PNP) is one of the most important enzymes of the purine metabolism, wich promotes the recycling of purine bases. Nowadays is the actual to search for effective inhibitors of this enzyme which is necessary for creation T-cell immunodeficient status of the organism in the organs and tissues transplantation, and ...
