A three-dimensional structure of Plasmodium falciparum serine hydroxymethyltransferase in complex with glycine and 5-formyl-tetrahydrofolate. Homology modeling and molecular dynamics

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.
