Meropenem binding to OXA-23. (A) Residual Fo-Fc electron density (pink) in the OXA-23 active site modeled with the final coordinates of meropenem (cyan ball-and-stick). Final 2Fo-Fc electron density for Ser79 is indicated. (B) Meropenem bound in the active site in the final model showing the hydrogen-bonding interactions (dashed black lines). See also Figure S2.
