Figure 5
Structural comparison among the complexes of SdgB. (a, b) All ligands and the key binding residues observed in the UDP-GlcNAc (a) and SD-repeat peptide (b) binding sites of SdgB complexes were superimposed for comparison. The ligands of SdgBquaternary are transparent. (c) Surface views of monomers of SdgBunbound and complexes. The surface views are colored depending on domains as in Fig. 2[link](a). Yellow dotted and black dotted lines indicate the angles and distances. White dotted circles between the DBD and ABD indicate the open and closed conformations of the active-site cleft.
