Figure 6. SOCKET analysis of the knobs-into-holes (KIH) packing for the Form I and Form II assemblies.

Figure 6

a, Atomic model of Form I filament for SOCKET analysis. b, Top (left) and side (right) view of consecutive KIH interactions (colored segments) at C-terminal ordered region of Form I helices. c, Atomic model of Form II filament for SOCKET analysis. d, Top (left) and side (right) view of consecutive KIH interactions (colored segments) in Form II filaments. KIH packing is limited to helices within the same wall (inner or outer). No helix-helix KIH packing is identified across the interface between inner and outer walls. The default packing cut-off of 7 Å was employed in the SOCKET analysis (http://coiledcoils.chm.bris.ac.uk/socket/server.html).
