The protozoan parasites Leishmania utilize a pteridine-reducing enzyme, pteridine reductase (PTR1), to bypass antifolate inhibition. The crystal structure of PTR1 from L. tarentolae has been solved as a binary complex with NADPH at 2.8 Å resolution. The structure was solved by molecular-replacement techniques using the recently reported L. major PTR1 structure as a search model. Comparisons of the present structure with the L. major PTR1 allowed us to identify regions of flexibility in the molecule. PTR1 is a member of the growing family of short-chain dehydrogenases (SDR) which share the characteristic Tyr(Xaa)3Lys motif in the vicinity of the active site. The functional enzyme is a tetramer and the crystallographic asymmetric unit contains a tetramer with 222 point-group symmetry.
