Molecular docking of 3QP8 structure of CviR protein of C. violaceum ATCC 12472 with 3-OH-C10-HSL, quercetin aglycone, quercetin 3-β-D-glucoside and furanone C-30. (A–D) surface representation of 3QP8 structure of CviR protein of C. violaceum ATCC 12472, (E–H) surface and backbone representations and (I–L) backbone representation with hydrogen bond between the amino acid residues and compounds evaluated. Gray surface representation, CviR protein; Red surface representation, 3-OH-C10-HSL; Yellow surface representation, quercetin aglycone; Green surface representation, quercetin 3-β-D-glucoside; Purple surface representation, furanone C-30; Gray backbone representation, CviR protein; Black arrow indicates the binding site; Yellow arrow, 3-OH-C10-HSL or quercetin aglycone or quercetin 3-β-D-glucoside or furanone C-30; Blue dashed line, hydrogen bond.
