distance geometry, simulated annealing, torsion angle dynamics, cns water refinement THE STRUCTURES ARE BASED ON A TOTAL OF 1690 RESTRAINTS. 1512 are NOE-DERIVED; SEQUENTIAL [(I-J)=1] = 201; MEDIUM RANGE [1<(I-J)<5] = 411; LONG RANGE [(I-J)>=5] = 900; HYDROGEN BOND RESTRAINTS = 80 (2 PER H-BOND); NUMBER OF NOE RESTRAINTS PER RESIDUE = 11.0 (RESIDES 2-138); DIHEDRAL-ANGLE RESTRAINTS = 178 (89 PHI, 89 PSI); TOTAL NUMBER OF RESTRAINTS PER RESIDUE = 12.2 (RESIDES 1-138); NUMBER OF LONG RANGE RESTRAINTS PER RESIDUE = 6.5; NUMBER OF STRUCTURES COMPUTED = 20; NUMBER OF STRUCTURES USED = 20. AVERAGE DISTANCE VIOLATIONS >0.1 ANG = 0; AVERAGE RMS DISTANCE VIOLATION / CONSTRAINT = 0.001 ANG.; MAXIMUM DISTANCE VIOLATION 0.038. AVERAGE DIHEDRAL ANGLE VIOLATIONS: >1 DEG = 0; MAX DIHEDRAL ANGLE VIOLATION = 0.73; AVERAGE RMS ANGLE VIOLATION / CONSTRAINT = 0.03 DEG. RMSD VALUES: BACKBONE ATOMS (N,C,C', RESIDUES 2-136) = 0.57 ANG; ALL HEAVY ATOMS = 0.93 ANG; PROCHECK (RESIDUES 2-136): MOST FAVORED REGIONS = 90%; ADDITIONAL ALLOWED REGIONS = 9%; GENEROUSLY ALLOWED REGIONS = 0%; DISALLOWED REGIONS = 1%. THE 8 RESIDUE C-TERMINAL HIS TAG (LEHHHHHH) WAS INCLUDED IN THE STRUCTURE CALCULATION. 1
