FIGURE 4.
Interface between the Acore and the MbtH-like domain of SlgN1. The interface is flipped open along the inner axis depicted as dashed lines. The MbtH-like domain (A, C, and E) is shown on the left, and the interfacing part of the Acore domain (B, D, and F) is shown on the right. A and B show a schematic, and C and D show a surface representation. E and F show the same representation of the opened interface but also the interfacing residues of the counterpart in a stick representation. The residue numbering in C and D corresponds to the surface residues, and the numbering in E and F corresponds to the sticks. Cα atoms are shown as small spheres. Yellow, nonpolar interactions; cyan, hydrogen bonding; green, hydrogen bonding and important nonpolar interactions (key residues); orange, salt bridging; yellow-orange, π-stacking interaction. Hydrogen bonds formed via main chain atoms are indexed with mc.
