Dynamic ion pair K11chainA–D52chainB interaction in cubic-PEG-ub crystals. a Crystallographic structure of cubic-PEG-ub (PDB entry 3N3045) and b a selected frame from cubic-PEG-ub trajectory. The dynamic disorder in residue K11chainA is reflected in its crystallographic temperature factors; this residue’s side chain has not been modeled in our recent structure 4XOL
