Human purine nucleoside phosphorylase double mutant E201Q,N243D complexed with 2-fluoroadenine
Template:ABSTRACT PUBMED 19388075
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]
About this Structure
3gb9 is a 3 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA.
