Docking of S. aureus FemA protein with ten FDA-approved drugs that are selected from the structure-based virtual screening. a Molecular interactions of Irinotecan with FemA protein. b Molecular interactions of Dexamethasone metasulfobenzoate with FemA protein. c Molecular interactions of Midostaurin with FemA protein. d Molecular interactions of Ergotamine with FemA protein. Grey ribbons represent the FemA protein, whereas yellow ball and stick models correspond to the drug molecules binding to the only active site. Hydrogen bonds between receptor and protein are represented using orange lines, and amino acids involved in the interaction are labelled.
