Crystal structure of cyclophilin from Leishmania donovani ligated with cyclosporin A

Publication Abstract from PubMed

Drug development against Leishmania donovani, the pathogen that causes visceral leishmaniasis in humans, is currently an active area of research given the widespread prevalence of the disease and the emergence of resistant strains. The immunosuppressive drug cyclosporin is known to have antiparasitic activity against a variety of pathogens. The receptor for cyclosporin is the protein cyclophilin, which is a ubiquitous peptidylprolyl isomerase. The crystal structure of cyclophilin from L. donovani complexed with cyclosporin has been solved at 2.6 A resolution. The thermodynamic parameters of the interaction have been determined using spectroscopic and calorimetric techniques. A detailed effort has been made to predict the thermodynamic parameters of binding from computations based on the three-dimensional crystal structure. These results were in good agreement with the corresponding experimental values. Furthermore, the structural and biophysical results have been discussed in the context of leishmanial drug resistance and could also set the stage for the design of potent non-immunosuppressive antileishmanials.
