26985580 Data (including data from empirical valence bond/molecular dynamic simulations) suggest that PNP substrate specificity for inosine and guanosine is a direct result of electrostatic preorganization energy along the reaction coordinate.
26305965 Data show that [15N, 2H]His8-purine nucleoside phosphorylase (PNP) had reduced catalytic site chemistry larger than proportional to the enzymatic mass difference.
25625196 the binding mechanism of a transition state analogue (DADMe-immucillin-H) to the purine nucleoside phosphorylase (PNP) enzyme, is reported.
25338677 Study of genetic heterogeneity in systemic lupus erythematosus, the top associations in European ancestry were protein kinase, cyclic GMP-dependent, type I (PRKG1) rs7897633 (P(Meta) = 2.75 x 10(-8)) and purine nucleoside phosphorylase (PNP) rs1049564 (P(Meta) = 1.24 x 10(-7)).
24792412 insufficient data to evaluated impact of genetic polymorphisms on disease susceptibility
24107682 Human small intestine is a key site for ribavirin phosphorolysis and that PNP is primarily involved in the metabolism.
22578971 Complete lack of PNP triggers accumulation of deoxyguanosine, thereby disrupting B-cell development, the consequence of which is more profound with time, as was found in the older sister.
22132981 Biochemical and genetic data on a cohort of seven patients from six families identified as PNPase deficient, is reported.
21448452 This study for the first time describes elevated levels of alpha synuclein in pancreatic adenocarcinoma as well as highlights the potential of evaluating NP protein expression.
