purine-nucleoside phosphorylase  M-CSA #695

Purine metabolism in the parasite Plasmodium has been identified as a promising target for antimalarial therapies due to slight alterations around the active site when compared to mammalian purine nucleoside phosphorylase (PNP). PNP is part of a salvage pathway for the biosynthesis of purines, which are essential to parasite survival due to location of the organism, erthrocytes and Plasmodium itself not being able to produce purines de novo .
