FIG. 4.
WecD acetyl-CoA binding site. (a) Stereo view of the Fo-Fc (omit) electron density around AcCoA from subunit A contoured at the 2.5 σ level. Residues interacting with AcCoA are indicated. (b) Interactions between AcCoA and WecD. Residues within 4 Å of CoA are shown. Hydrogen bonds are marked by dashed lines.
