Figure 5

Hexamer formation. (A) The P6 space group constrains the hexamer to be symmetric, as shown in this view of the assembly in which one subunit is highlighted in yellow. (B) In both ADP and ATP-bound P6 crystal forms, the main intermolecular interface is CTDn:NTDn+1 as seen in these two adjacent subunits, viewed perpendicular to the 6-fold symmetry axis. Black outlines the non-covalent CTDn:NTDn+1 pair. (C) Zoomed-in stereo view of the intermolecular CTDn:NTDn+1 interface, rotated to highlight a subset of the amino acids in the polar interface. The coloring in all panels is as in Figure 2.
