The X-ray structure of the S. aureus PBP 2a (left) is shown as a solvent-accessible Connolly surface in green. The close up of the active site (at one o’clock) is depicted in stereo, showing the fitting of compound 1 in the pose predicted by the program DOCK. Inhibitor color scheme: oxygen (red), nitrogen (blue), carbon (gray), and fluorine (aqua).
