NONE OF THE STRUCTURES EXHIBITED VIOLATIONS GREATER THAN 0.5 ANGSTROMS. *(2)* FOR EACH BACKBONE HYDROGEN BOND THERE ARE TWO RESTRAINTS - R(NH-O) .LT. 2.3 ANGSTROMS AND R(N-O) .LT. 3.3 ANGSTROMS. THE LOWER LIMITS ARE GIVEN BY THE SUM OF THE VAN DER WAALS RADII OF THE RELEVANT ATOMS. *(3)* THE VALUES OF THE SQUARE-WELL NOE POTENTIAL F(NOE) ARE CALCULATED WITH A FORCE CONSTANT OF 50 KCAL/MOL/ANGSTROM**2. *(4)* THE VALUES OF F(PHI) ARE CALCULATED WITH A FORCE CONSTANT OF 200 KCAL/MOL/RAD**2. F(PHI) IS A SQUARE-WELL DIHEDRAL POTENTIAL WHICH IS USED TO RESTRICT THE RANGES OF 33 PHI ,24 PSI AND 25 CHI1 TORSION ANGLES. *(5)* THE VALUE OF THE VAN DER WAALS REPULSION TERM F(REPEL) IS CALCULATED WITH A FORCE CONSTANT OF 4 KCAL/MOL/ANGSTROM**4 WITH THE HARD SPHERE VAN DER WAALS RADII SET TO 0.8 TIMES THE STANDARD VALUES USED IN THE *CHARMM* EMPIRICAL ENERGY FUNCTION. *(6)* THE IMPROPER TERMS SERVE TO MAINTAIN PLANARITY AND APPROPRIATE CHIRALITY. THEY ALSO MAINTAIN THE PEPTIDE BONDS OF ALL RESIDUES (WITH THE EXCEPTION OF PROLINES) IN THE TRANS CONFORMATION. IN THE DYNAMICAL SIMULATED ANNEALING CALCULATIONS, THE RESTRAINTS FOR THE DISULFIDE BRIDGES ARE INCLUDED IN THE BOND AND ANGLE TERMS. A TOTAL OF 32 STRUCTURES CONSISTENT WITH THE NMR DATA WERE CALCULATED. THIS ENTRY REPRESENTS THE COORDINATES OBTAINED BY AVERAGING THE COORDINATES OF THE INDIVIDUAL STRUCTURES AND SUBJECTING THE RESULTING COORDINATES TO FURTHER RESTRAINED MINIMIZATION. THE COORDINATES OF THE 32 STRUCTURES ARE GIVEN IN THE PROTEIN DATA BANK ENTRY *2HIR*. THE THERMAL PARAMETERS GIVEN IN THIS ENTRY REPRESENT THE ATOMIC RMS DEVIATION OF THE INDIVIDUAL STRUCTURES ABOUT THE MEAN COORDINATE POSITIONS. ONLY RESIDUES 1-49 ARE WELL DEFINED. RESIDUES 50-65 FORM A DISORDERED C-TERMINAL TAIL. | ||||||||
