== Publication Abstract from PubMed ==
 +
This work describes for the first time the structure of purine nucleoside phosphorylase from Mycobacterium tuberculosis (MtPNP) in complex with sulfate and its natural substrate, 2'-deoxyguanosine, and its application to virtual screening. We report docking studies of a set of molecules against this structure. Application of polynomial empirical scoring function was able to rank docking solutions with good predicting power which opens the possibility to apply this new criterion to analyze docking solutions and screen small-molecule databases for new chemical entities to inhibit MtPNP.
