A Predicted binding mode of LM to the active site of CTX-M-15 (PDB: 5T66). The ligand (GQAs) is shown as CPK-colored thick sticks. The amino acids in the active site are shown as sticks. Electrostatic surface potential (ESP) of the protein active site is shown; Red represents negatively charged (acidic) ESP and Blue is for positive (basic) ESP. Green dashed lines represents the hydrogen bonds between the ligand and the protein MOE Docking score (S Score) of the pose selected = − 7.8 kcal/mol. B 2 D interaction diagram of interaction between GQAs and the active site amino acids of CTX-M-15 (PDB: 5T66). The solvent accessible surface is shown by light blue shades
