Fig. 7: The binding mode of CE in WT AtAHAS and in the P197T mutant.
From: Structural basis of resistance to herbicides that target acetohydroxyacid synthase
a The interactions of CE with WT AtAHAS (PDB code: 5K3S13). b The interactions of CE with the P197T mutant. ThDP is degraded to ThAThDP (light brown). The black thin lines represent CE from the WT AtAHAS:CE structure that has been superimposed with the P197T-CE structure. (a, b) CE is in green and in ball and stick representation. The FAD is in yellow and in stick representation. Dashed lines represent hydrogen bonds (black). Grey dashed cylinders represent π–π interactions. Yellow dashed cylinders represent sulfur–π interactions. Blue dashed cylinders represent hydrophobic interactions. Pale brown spheres represent the geometric centers of the aromatic groups.
