SUMMARY OF RBFA STRUCTURE CALCULATION BY AUTOSTRUCTURE: SUMMARY OF EXPERIMENTAL CONSTRAINTS: DISTANCE CONSTRAINTS: TOTAL = 1698; INTRA-RESIDUE [I=J] = 175; SEQUENTIAL [(I-J)=1] = 454; MEDIUM RANGE [1<(I-J)<5] = 595; LONG RANGE [(I-J)>=5] = 474; NUMBER OF DISTANCE CONSTRAINTS PER RESIDUE = 15.7; DIHEDRAL-ANGLE CONSTRAINTS = 184; TOTAL HYDROGEN BOND CONSTRAINTS = 88; LONG RANGE HYDROGEN BOND CONSTRAINTS = 24; TOTAL NUMBER OF CONSTRAINTS PER RESIDUE = 18.2; NUMBER OF LONG RANGE CONSTRAINTS PER RESIDUE = 4.6; NUMBER OF STRUCTURES COMPUTED = 200; NUMBER OF STRUCTURES USED = 16. RESIDUAL CONSTRAINT VIOLATIONS: DISTANCE VIOLATIONS 0.1-0.2ANG = 31; 0.2-0.5ANG = 9; >0.5ANG = 1. MAX DISTANCE VIOLATION = 0.57ANG; AVERAGE DISTANCE VIOLATION = 0.00ANG. MAX. VDW VIOLATION = 0.37 ANG. DIHEDRAL ANGLE VIOLATIONS: 0 - 10 DEG = 6; >10 DEG = 0; MAX ANGLE VIOLATION = 9 DEG; AVERAGE ANGLE VIOLATION = 0.06 DEG. RMSD VALUES : ALL BACKBONE ATOMS OF ALL RESIDUES = 0.5 ANG; ALL BACKBONE ATOMS OF ORDERED RESIDUES = 0.5 ANG; ALL HEAVY ATOMS OF ALL RESIDUES = 1.0 ANG; ALL HEAVY ATOMS OF ORDERED RESIDUES = 1.0 ANG. PROCHECK USING ALL RESIDUES: MOST FAVORED REGIONS = 73%; ADDITIONAL ALLOWED REGIONS = 23%; GENEROUSLY ALLOWED REGIONS = 4%; DISALLOWED REGIONS = 0%. NMR R-FACTORS : M = 39% I=46% L=27% . SPECTRAL INFORMATION: TOTAL NUMBER OF PEAKS IN N15-NOESY = 1536; TOTAL NUMBER OF ASSIGNABLE PEAKS IN N15- NOESY = 1239; TOTAL NUMBER OF PEAKS ASSIGNED IN N15-NOESY = 814; TOTAL NUMBER OF PEAKS IN C13-NOESY = 3115; TOTAL NUMBER OF ASSIGNABLE PEAKS IN C13-NOESY = 2494; TOTAL NUMBER OF PEAKS ASSIGNED IN C13-NOESY = 1802.
