Method RESTRAINED SIMULATED IN TORSION ANGLE SPACE
Details THE STRUCTURES WERE CALCULATED BY SIMULATED ANNEALING IN TORSION ANGLE SPACE (C. SCHWIETERS AND G.M. CLORE. IN PRESS). THE TARGET FUNCTION COMPRISES TERMS FOR THE NOE RESTRAINTS, TORSION ANGLE RESTRAINTS, CARBON CHEMICAL SHIFT RESTRAINTS (KUSZEWSKI ET AL. J. MAGN. RESON. SERIES B 106, 92-96 (1995)), THE DIPOLAR COUPLING RESTRAINTS (CLORE ET AL. J.MAGN.RESON. 131, 159-162 (1998); J.MAGN.RESON. 133, 216-221(1998)), THE RADIUs OF GYRATION (KUSZEWSKI ET AL. (1999), AND A QUARTIC VAN DER WAALS REPULSION TERM (NILGES ET AL. (1988) FEBS LETT. 229, 129-136). IN THIS ENTRY THE LAST COLUMN REPRESENTS THE AVERAGE RMS DIFFERENCE BETWEEN THE INDIVIDUAL SIMULATED ANNEALING STRUCTURES AND THE MEAN COORDINATE POSITIONS. ONLY COORDINATES FOR RESIDUES 1-50 (LAP2-N) and 111-153 (LAP2-C) ARE PROVIDED. THE LINKER CONNECTING THESE TWO DOMAINS IS COMPLETELY DISORDERED. LIKEWISE THE C-TERMINAL RESIDUES (154-168) ARE DISORDERED. SINCE THE TWO DOMAINS, LAP2-N AND LAP2-C, REORIENT ESSENTIALLY INDEPENDENTLY IN SOLUTION, THE COORDINATES OF THE TWO DOMAINS HAVE BEEN BEST-FITTED TO EACH OTHER SINCE THEY ARE STRUCTURALY VERY SIMILAR. THE LAP2-N DOMAIN BINDS DNA. THE LAP2-C DOMAIN BINDS THE BARRIER-TO-AUTOINTEGRATION FACTOR BAF.
