Cytosolic Plasmodium falciparum serine hydroxymethyltransferase (pfSHMT) is a potential target for antimalarial chemotherapy. Contrasting with the other enzymes involved in the parasite folate cycle, little information is available about this enzyme, and its crystallographic structure is unknown yet. In this paper, we propose a theoretical low-resolution 3D model for pfSHMT in complex with glycine and 5-formyl tetrahydrofolate (5-FTHF) based on homology modeling by multiple alignment followed by intensive optimization, validation and dynamics simulations in water. Comparison between the active sites of our model and that of crystallographic Human SHMT (hSHMT) revealed key differences that could be useful for the design of new selective inhibitors of pfSHMT.
