Stereo diagram of inhibitors binding to active site of PfA-M17. (A) 2.0 Å PfA-M17-BES and (B) 2.6 Å PfA-M17-Co4 active site showing inhibitors bound in the active site. Inhibitors (BES/Co4) are colored in magenta. Carbon atoms of residues are colored green. Zinc is shown as black sphere; Magnesium as yellow sphere and water molecules are light-blue spheres. Hydrogen and metallo-bonds are indicated (dashed lines). Electron density is a composite omit map showing averaged density of 12 protein chains contoured at 3.0 σ calculated by using a model containing only PfA-M17 atoms (no metal, ligand, or water was included in calculation).
