== Publication Abstract from PubMed ==
Pteridine reductase (PTR1) is a potential target for drug development against parasitic Trypanosoma and Leishmania species. These protozoa cause serious diseases for which current therapies are inadequate. High-resolution structures have been determined, using data between 1.6 and 1.1 A resolution, of T. brucei PTR1 in complex with pemetrexed, trimetrexate, cyromazine and a 2,4-diaminopyrimidine derivative. The structures provide insight into the interactions formed by new molecular entities in the enzyme active site with ligands that represent lead compounds for structure-based inhibitor development and to support early-stage drug discovery.


==About this Structure==
High-resolution structures of Trypanosoma brucei pteridine reductase ligand complexes inform on the placement of new molecular entities in the active site of a potential drug target.,Dawson A, Tulloch LB, Barrack KL, Hunter WN Acta Crystallogr D Biol Crystallogr. 2010 Dec;66(Pt 12):1334-40. Epub 2010, Nov 16. PMID:21123874<ref>PMID:21123874</ref>
