CRYSTAL STRUCTURE OF HUMAN PNP COMPLEXED WITH ACYCLOVIR

Template:ABSTRACT PUBMED 12914786

Disease

[PNPH_HUMAN] Defects in PNP are the cause of purine nucleoside phosphorylase deficiency (PNPD) [MIM:613179]. It leads to a severe T-cell immunodeficiency with neurologic disorder in children.^[1][2][3]

Function

[PNPH_HUMAN] The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta-(deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.^[4]
