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% .
