== Publication Abstract from PubMed ==
A novel strategy for targeting the pathogenic organisms Candida albicans and Candida glabrata focuses on the development of potent and selective antifolates effective against dihydrofolate reductase. Crystal structure analysis suggested that an essential loop at the active site (Thr 58-Phe 66) differs from the analogous residues in the human enzyme, potentially providing a mechanism for achieving selectivity. In order to probe the role of this loop, we employed chemical synthesis, crystal structure determination and molecular dynamics simulations. The results of these analyses show that the loop residues undergo ligand-induced conformational changes that are similar among the fungal and human species.

Structural analysis of the active sites of dihydrofolate reductase from two species of Candida uncovers ligand-induced conformational changes shared among species.,Paulsen JL, Viswanathan K, Wright DL, Anderson AC Bioorg Med Chem Lett. 2013 Mar 1;23(5):1279-84. doi: 10.1016/j.bmcl.2013.01.008. , Epub 2013 Jan 11.
