Fig. 4: Interactions of BHA and its derivatives with Pst_13661.
From: Inhibition of chitin deacetylases to attenuate plant fungal diseases
a–c Amino acid residues involved in the binding of BHA (a), compound 2 (b), and compound 3 (c) within the active site of Pst_13661. BHA, compound 2, and compound 3 are shown as sticks with yellow, green, and light pink carbon atoms, respectively. The 2Fo-Fc electron-density map around the ligands is contoured at the 1.0 σ level. The Pst_13661 residues that interact with these compounds are shown as sticks with blue carbon atoms. Hydrogen bonds are shown as dashed lines. The zinc ions and water molecules are shown as slate and red spheres, respectively. The amino acids are labeled by their one-letter abbreviations.
