Putative binding poses of ligands docked with TEM-72, SHV-2 and topoisomerase IV. The yellow dotted line indicates the H-bonding between the ligand and protein. a Molecular interaction of ligand benzoic acid-4-ethoxy-ethyl ester with TEM-72. b Molecular interaction of ligand farnesol acetate with SHV-2. c Molecular interaction of ligand farnesol acetate with Topoisomerase IV
