Structural determinants of the 5'-methylthioinosine specificity of Plasmodium purine nucleoside phosphorylase. [PDF]

open access: yesPLoS ONE, 2014
Plasmodium parasites rely upon purine salvage for survival. Plasmodium purine nucleoside phosphorylase is part of the streamlined Plasmodium purine salvage pathway that leads to the phosphorylysis of both purines and 5'-methylthiopurines, byproducts of ...
