The molecular model, corresponding to the open-tense FtsZ complexed with the reference ligand PC190723 coded as 4dxd (Research Collaboratory for Structural Bioinformatics, RCSB, Protein Data Bank PDB ID) of Staphylococcus aureus was selected for the studies. For docking, this target including their GDP nucleotide and idc cavity were centered around a 45x45x45 Å grid surrounding most of the whole FtsZ molecule.
