Fig. 1.

The docking poses and 2-D ligand–protein interaction diagrams of 7BRP and the top three ligands: A, Petunidin 3-O-(6″-p-coumaroyl-glucoside); B, Malvidin 3,5-O-diglucoside; C, Cyanidin 3-O-(6″-p-coumaroyl-glucoside). For the docking poses, S1/S2 subsites are being shown. The purple arrow indicates the hydrogen bond; the green line represents π-π stacking; the red line represents π -cation interaction.
