The interaction between TsENO and human PLG. A TsENO and PLG bound to each other at the interface region. TsENO is shown in cyan, and PLG is shown in blue. Interface-located residues of TsENO are shown in green, and those of PLG are shown in red. B The important residues (Lys90, Lys289, Lys291 and Lys300) for PLG binding are shown in red in the Corey-Pauling-Koltun (CPK) model. C TsENO-PLG interaction plot. TsENO residues are shown above the dashed line, and PLG residues are shown in different colours beneath the dashed line. Hydrogen bonds are shown as green dashed lines and labelled with the bond length (Å). The arcs represent the other residues involved in the TsENO-PLG interaction.
