    Details STRUCTURES DETERMINED BY THE HYBRID METRIC MATRIX DISTANCE GEOMETRY-DYNAMICAL SIMULATED ANNEALING METHOD OF M. NILGES, G. M. CLORE, AND A. M. GRONENBORN (FEBS LETT. 229, 317 (1988)). THE STRUCTURES ARE BASED ON 1983 INTERPROTON DISTANCE RESTRAINTS DERIVED FROM NOE MEASUREMENTS; 52 HYDROGEN-BONDING DISTANCE RESTRAINTS FOR 26 HYDROGEN-BONDS IDENTIFIED ON THE BASIS OF THE NOE AND AMIDE PROTON EXCHANGE DATA, AS WELL AS THE INITIAL STRUCTURE CALCULATIONS; AND 98 PHI AND 71 PSI BACKBONE TORSION ANGLE RESTRAINTS AND 72 CHI1 SIDE-CHAIN TORSION ANGLE RESTRAINTS DERIVED FROM COUPLING CONSTANTS AND NOE DATA. A TOTAL OF 33 STRUCTURES WERE CALCULATED. THIS STRUCTURE REPRESENTS THE MINIMIZED AVERAGE STRUCTURE. THIS IS OBTAINED BY AVERAGING THE COORDINATES OF THE INDIVIDUAL STRUCTURES AND SUBJECTING THE RESULTING COORDINATES TO RESTRAINED MINIMIZATION. THE ENTIRE SET OF 33 STRUCTURES CAN BE FOUND IN PDB ENTRY 4TRX. THE LAST COLUMN IN THIS COORDINATE FILE REPRESENTS THE ATOMIC RMS DEVIATION OF THE INDIVIDUAL STRUCTURES ABOUT THE MEAN COORDINATE POSITIONS.
