Fig. 4.

The full-particle model of TRiC in the OMS arrangement is shown in top (A) and side (B) views, with a different color for each subunit type. The inter-subunit cross-links are drawn to scale with their atoms as black Van der Waals spheres. Two solid slices through both the upper and lower rings (C) are annotated with the subunit order. The CCT2(β) subunits (green) in the upper and lower rings are in contact as are the CCT6(ζ) subunits (brown). For clarity, the back half of the particle in each view is not shown and the Van der Waals radii of the atoms in the cross-links are increased by 30%. The order of subunits in the top ring is αγζθηϵβδ or CCT1, CCT3, CCT6, CCT8, CCT7, CCT5, CCT2, CCT4 (13687524) that we prefer to write as AGZQHEBD.
