| simulated annealing | The structures are based on a total of 2066 restraints, 1999 are NOE-derived distance restraints, of which 58 are intermolecular. For the S5a ubiquitin-interacting motif only the residues 270 to 301 were included in the structure calculations due to disorder of the flexible N- and C-termini. | XwinNMR |
