Figure 4
Electron density for FabH ligands. OCoA is shown as black sticks and labeled FabH active-site residues as white sticks. The σA-weighted mFo − DFc maps are shown at +3σ in green and −3σ in red as 5 Å bricks for (a) omitted OCoA, Cys112 Cβ and sulfur or (b) Cys112 Cβ, sulfur and acetyl group. (a) is Ac-FabH + OCoA and (b) is FabH + OCoA. Note that a water molecule takes the place of the acetyl-cysteine carbonyl. |
