Figure 2. Observed FoFc and 2FoFc electron density assigned to fusidic acid located at the TM1-TM2 groove of the AcrB T protomer.

Figure 2

(a) Simulated annealing (SA) composite omit 2mFo-DFc electron density (grey mesh, contoured at 1.2σ, 0.8167, e Å3) and SA composite omit mFo-DFc electron density (red mesh, contoured at 1.9σ (1.1086, e Å3) at the TM1/TM2 groove of the Tight protomer. (b) As in a with the assignment of a fusidic acid molecule (FUA, grey stick) in the SA composite omit 2mFo-DFc electron density (before refinement). Residues I27, I337, H338 and V341 (cyan sticks) interact with fusidic acid.
