| simulated annealing | Starting models for ZZ-domain of CBP is 1TOT and apo-structure of SUMO1 is 1A5R. In both cases author used the first model in the ensemble as starting structure for the RDC-refinement. In the case of the ZZ-domain, used published structural restraints from BMRB in combination with RDCs measured on the complex. For SUMO1, constructed synthetic distance restraints from proton-proton distances (since no published restraints were available for apo-SUMO1) and used these for refinement along with RDCs measured on the complex. Xplor-NIH and a simulated annealing protocol were used for all refinement work and Haddock/CNS was used for generating the complex. | X-PLOR NIH |
