Figure 1.

Overview of ligand binding to the PfHsp70-x ATPase domain. Shown here are the two ligand-interaction sites of the ATPase domain of PfHsp70-x identified by crystallographic fragment screening. (a) and (b) display the domain structure in perpendicular views, with the interaction sites highlighted. The main binding site (site 1) is proximal to the ATPase nucleotide-binding pocket. Ligands and the hydrolysed nucleotide bound to this domain, modelled as AMP-PN plus a leaving phosphate group, are shown as sticks.
