REMARK 3 PROGRAM : X-PLOR NIH REMARK 3 AUTHORS : SCHWIETERS, KUSZEWSKI, TJANDRA AND CLORE REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: REMARK 3 STARTING MODELS FOR ZZ-DOMAIN OF CBP IS 1TOT AND APO-STRUCTURE OF REMARK 3 SUMO1 IS 1A5R. IN BOTH CASES AUTHOR USED THE FIRST MODEL IN THE REMARK 3 ENSEMBLE AS STARTING STRUCTURE FOR THE RDC-REFINEMENT. IN THE CASE REMARK 3 OF THE ZZ-DOMAIN, USED PUBLISHED STRUCTURAL RESTRAINTS FROM BMRB REMARK 3 IN COMBINATION WITH RDCS MEASURED ON THE COMPLEX. FOR SUMO1, REMARK 3 CONSTRUCTED SYNTHETIC DISTANCE RESTRAINTS FROM PROTON-PROTON REMARK 3 DISTANCES (SINCE NO PUBLISHED RESTRAINTS WERE AVAILABLE FOR APO- REMARK 3 SUMO1) AND USED THESE FOR REFINEMENT ALONG WITH RDCS MEASURED ON REMARK 3 THE COMPLEX. REMARK 3 XPLOR-NIH AND A SIMULATED ANNEALING PROTOCOL WERE USED FOR ALL REMARK 3 REFINEMENT WORK AND HADDOCK/CNS WAS USED FOR GENERATING THE REMARK 3 COMPLEX.
