Figure 6.

Model for the (CCAN)2 – Cenp-ANuc complex. (A) Two orthogonal views of the complex showing how Cenp-ANuc slots into the groove formed by the association of two ‘Y’-shaped CCAN protomers. The unwrapped DNA at the two Cenp-ANuc termini engage the DNA-binding groove of Cenp-LN at the centre of each CCAN protomer. (B) Close-up view of the interaction between Cenp-HIKHead-TW and Cenp-OPQU+ of the symmetry-related protomer with Cenp-OPQU+ shown in surface representation. There is a slight clash of Cenp-TW with Cenp-OPQU+.
