The figure (A) shows the licochalcone B–DBP complex. In figure (B) salt bridges and hydrogen bonds formed during the docking experiment are depicted in green and red color, respectively. One oxygen atom of daidzein forms a salt bridge and a hydrogen bond with Arg274 with a bond length of 2.12 Å. On the other hand, another oxygen atom forms a salt bridge with Lys366, and the length of the salt bridge is 1.63 Å.
