Figure 2.

The left-hand panels show the binding site for each ligand: (a) the thienopyrimidine 6KV, (b) the piperidinylindole 7AH, (c) the aminoacylpyrrolidine A6K and (d) the biphenyl derivative CWZ. The structures are coloured by atom; carbon, green for protein and grey for ligand; oxygen, red; nitrogen, blue; sulfur, yellow; fluorine, silver; chlorine, mauve. Selected water molecules within 3.5 Å of the ligands are also shown. For clarity, the co-substrate MyrCoA is not shown. Stereoviews (including the co-substrate) of the binding site are presented in Supplementary Fig. S2. The right-hand panel shows the final refined electron-density map associated with bound ligand (2mF _o − DF _c) contoured at a level of 1σ.
