NMR Refinement
Method	Details	Software
The initial structure was determined using automated structure determination (AutoStructure) and refined manually. A final refinement used simultated annealing in explicit solvent.	THE STRUCTURES ARE BASED ON A TOTAL OF 1039 RESTRAINTS. SUMMARY OF EXPERIMENTAL CONSTRAINTS: RESTRAINING DISTANCE RESTRAINTS: TOTAL = 864; INTRA-RESIDUE [I=J] = 160; SEQUENTIAL [(I-J)=1] = 225; MEDIUM RANGE [1<(I-J)<5] = 131; LONG RANGE [(I-J)>=5] = 348; HYDROGEN BOND RESTRAINTS = 72 (2 PER H-BOND); NUMBER OF RESTRAINING DISTANCE RESTRAINTS PER RESTRAINED RESIDUE = 8.2; DIHEDRAL-ANGLE RESTRAINTS = 103 (50 PHI, 52 PSI, 1 CHI-1); TOTAL NUMBER OF RESTRAINTS PER RESTRAINED RESIDUE = 8.9; NUMBER OF LONG RANGE NOE DISTANCE RESTRAINTS PER RESTRAINED RESIDUE = 3.0; NUMBER OF STRUCTURES COMPUTED = 30; NUMBER OF STRUCTURES USED = 20. AVERAGE DISTANCE VIOLATIONS >0.0001 ANG = 26.8+/-6; AVERAGE R.M.S. DISTANCE VIOLATION = 0.005 +/- 0.001 ANG; MAXIMUM NUMBER OF DISTANCE VIOLATIONS 39.MAXIMUM DISTANCE VIOLATION = 0.26 ANG; AVERAGE DIHEDRAL ANGLE VIOLATIONS: >0.0001 DEG = 3.3+/-1.3; MAX NUMBER OF DIHEDRAL ANGLE VIOLATIONS = 5; AVERAGE R.M.S. ANGLE VIOLATION = 0.42 +/- .01 DEG.; RMSD VALUES: BACKBONE ATOMS (N,C,C' RESIDUES 10-126) = 0.86 ANG, ALL HEAVY ATOMS = 1.52 ANG; BACKBONE ATOMS (N,C,C' RESIDUES 33-126) = 0.68 ANG, ALL HEAVY ATOMS = 1.1.38 ANG; BACKBONE ATOMS (N,C,C' RESIDUES 12-16,24-26,34-39,41-49,52-74,79-92,95-114,119-126) = 0.67 ANG,ALL HEAVY ATOMS = 1.19 ANG; PROCHECK (RESDIUES 10-126): MOST FAVORED REGIONS = 83.8%; ADDITIONAL ALLOWED REGIONS = 14.9%; GENEROUSLY ALLOWED REGIONS = 1.9%; DISALLOWED REGIONS = 0.4%.
