Figure 5.
HADDOCK-derived model for the PFUC-Ub complex. A, backbone
superposition of 10 refined cis-PFUC-Ub complex structures. The
average energy for the cluster is −6349 ± 59
kcal·mol^−1 for the cis-PFUC-Ub complex and that is
−6377 ± 81 kcal·mol^−1 for trans-PFUC-Ub. The
root mean square deviation of all backbone atoms in the
interfaces is 1.2 ± 0.8 Å for cis-PFUC-Ub and 1.1
± 0.9 Å for trans-PFUC-Ub. B, close-up view of the
interfaces showing the side chains of key interacting residues.
The stick representations are in red for the side chains from Ub
and in blue for those from PFUC.
