Binding mode of dafachronic acids on model of DimDAF-12 ligand binding domain. A In silico docking of dafachronic acids (DAs) into the model of DimDAF-12 LBD was performed using Autodock. Δ4-DA and Δ7-DA bind inside the ligand binding pocket of DimDAF-12. The structures of Δ4-DA (B) and Δ7-DA (C) differ in the position of an unsaturated double bond respectively at C4 or C7 of the steroid nucleus. H-bonds are illustrated by yellow dashed lines with bond lengths noted in Å. All images were generated using PyMol 1.3 (https://pymol.org/2/).
