AVERAGE DISTANCE VIOLATIONS >0.1 ANG = 0; AVERAGE RMS DISTANCE VIOLATION / CONSTRAINT = 0.004 ANGSTROMS.; MAXIMUM DISTANCE VIOLATION 0.05. AVERAGE DIHEDRAL ANGLE VIOLATIONS: >10 DEG = 0; MAX DIHEDRAL ANGLE VIOLATION = 0.45; AVERAGE RMS ANGLE VIOLATION / CONSTRAINT = 0.14 DEG. RMSD VALUES: BACKBONE ATOMS (N,C,C', RESIDUES 11-20,33-68) = 0.4 ANG; ALL HEAVY ATOMS = 0.9 ANG; PROCHECK (RESIDUES 11-20,33-68): MOST FAVORED REGIONS = 95%; ADDITIONAL ALLOWED REGIONS = 5%; GENEROUSLY ALLOWED REGIONS = 0%; DISALLOWED REGIONS = 1%. 6 NON-NATIVE N-TERMINAL RESIDUES (MAGDPL) AND 8 C-TERMINAL RESDIUES, INLUDING THE HIS TAG, (LEHHHHHH) WERE INCLUDED IN THE STRUCTURE CALCULATION.
