Figure 3

Free energy barriers for deacylation of carbapenem ACs with the 6α-hydroxyethyl group in the three different orientations. Each bar includes the barrier obtained with a single water molecule hydrogen bonded to Lys73:OQ2 (lowest barrier, in color; see Figure 4 for depiction of OQ2) and the barrier obtained with two water molecules hydrogen bonded to Lys73:OQ2 (highest barrier, in gray). Each barrier is derived from three individual US simulations, with standard deviations in parenthesis. IME: green, MER: pink.
