| + | == Function == | ||
| + | [https://www.uniprot.org/uniprot/PUNA_MYCTU PUNA_MYCTU] 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. Cleaves guanosine and inosine (By similarity). | ||

| + | == 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. | ||
