Lb NDK hexamer interfaces. (A) Side and top views of the hexamer, with each subunit in a different color (red, orange and cyan in the bottom trimer; purple, yellow and green in the top trimer). (B) Dimeric interface regions from two different subunits (purple and cyan) with an inset corresponding to the zoom view that shows residues (sticks) involved in dimer stabilization via hydrogen bonds (dotted black lines) and the electronic density map for these residues. (C) Trimeric interface region between the purple and green subunits highlighting residues (sticks) that make hydrogen bonds (dotted black lines) and the electronic density map for these residues.
