Best docking conformation of bile acids with CsMRP4. The 3D model of CsMRP4 is visualized as a white ribbon diagram, which is depicted in transparency (90%) to show the bile acid docked deep into the inner cavity (a). The red circle indicates the inner cavity for bile acid binding. The results are arranged according to the order of calculated binding affinities of complex bile acid-CsMRP4, as listed in Table 2: b TLCA, c LCA, d TCDCA, e CDCA, f TDCA, g TCA, h GCA, i DCA, j CA
