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 935 RESTRAINTS. SUMMARY OF EXPERIMENTAL CONSTRAINTS RESTRAINING DISTANCE RESTRAINTS: TOTAL = 758; INTRA-RESIDUE [I=J] = 174; SEQUENTIAL [(I-J)=1] = 174; MEDIUM RANGE [1<(I-J)<5] = 109; LONG RANGE [(I-J)>=5] = 301; HYDROGEN BOND RESTRAINTS = 56 (2 PER H-BOND); NUMBER OF RESTRAINING DISTANCE RESTRAINTS PER RESTRAINED RESIDUE = 7.3; DIHEDRAL-ANGLE RESTRAINTS = 121 (60 PHI, 59 PSI, 2 CHI-1); TOTAL NUMBER OF RESTRAINTS PER RESTRAINED RESIDUE = 8.3; NUMBER OF LONG RANGE NOE DISTANCE RESTRAINTS PER RESTRAINED RESIDUE = 2.7; NUMBER OF STRUCTURES COMPUTED = 40; NUMBER OF STRUCTURES USED = 20; AVERAGE DISTANCE VIOLATIONS >0.0001 ANG = 19.8 +/- 3.5; AVERAGE R.M.S. DISTANCE VIOLATION = 0.0009 +/- 0.0003 ANG; MAXIMUM NUMBER OF DISTANCE VIOLATIONS 25; MAXIMUM DISTANCE VIOLATION = 0.03 ANG; AVERAGE DIHEDRAL ANGLE VIOLATIONS: >0.0001 DEG = 2.5+/-1.3; MAX NUMBER OF DIHEDRAL ANGLE VIOLATIONS = 4; AVERAGE R.M.S. DIHEDRAL ANGLE VIOLATION = 0.02 +/- .01 DEG.; RMSD VALUES TO AVERAGE STRUCTURE: BACKBONE ATOMS (N,C,C' RESIDUES 12-125) = 0.88 ANG, ALL HEAVY ATOMS = 1.38 ANG; BACKBONE ATOMS (N,C,C' RESIDUES 32-122) = 0.71 ANG, ALL HEAVY ATOMS = 1.21 ANG; BACKBONE ATOMS (N,C,C' RESIDUES 16-17,21-36,39-41,44-46,53-73,76-122) = 0.70 ANG, ALL HEAVY ATOMS = 1.14 ANG; PROCHECK (RESIDUES 16-17,21-36,39-41,44-46,53-73,76-122): MOST FAVORED REGIONS = 84.6%; ADDITIONAL ALLOWED REGIONS = 14.0%; GENEROUSLY ALLOWED REGIONS = 0.2%; DISALLOWED REGIONS = 1.2%; PROCHECK (RESIDUES 12-125): MOST FAVORED REGIONS = 77.8%; ADDITIONAL ALLOWED REGIONS = 19.2%; GENEROUSLY ALLOWED REGIONS = 2.0%; DISALLOWED REGIONS = 1.0%.
