    Details DETAILS OF THE STRUCTURE DETERMINATION AND ALL STRUCTURAL STATISTICS ARE GIVEN IN THE PAPER CITED ON *JRNL* RECORDS ABOVE (I.E. AGREEMENT WITH EXPERIMENTAL RESTRAINTS, DEVIATIONS FROM IDEALITY FOR BOND LENGTHS, ANGLES, PLANES AND CHIRALITY, NON-BONDED CONTACTS, ATOMIC RMS DIFFERENCES BETWEEN THE CALCULATED STRUCTURES). THE STRUCTURES ARE BASED ON 1827 INTERPROTON DISTANCE RESTRAINTS DERIVED FROM NOE MEASUREMENTS; 148 HYDROGEN-BONDING DISTANCE RESTRAINTS FOR 74 HYDROGEN-BONDS IDENTIFIED ON THE BASIS OF THE NOE AND AMIDE PROTON EXCHANGE DATA, AS WELL AS THE INITIAL STRUCTURE CALCULATIONS; 24 RESTRAINTS FOR THE 4 CALCIUM IONS, AND 113 PHI TORSION ANGLE RESTRAINTS DERIVED FROM COUPLING DATA, CONSTANTS, NOE AND 13C SECONDARY CHEMICAL SHIFTS. THE METHOD USED TO DETERMINE THE STRUCTURES IS THE HYBRID METRIC MATRIX DISTANCE GEOMETRY-DYNAMICAL SIMULATED ANNEALING METHOD [M.NILGES, G.M.CLORE, AND A.M.GRONENBORN, FEBS LETT. 229, 317-324 (1988)]. A TOTAL OF 21 STRUCTURES WERE CALCULATED. THE COORDINATES OF THE RESTRAINED MINIMIZED STRUCTURE ARE PRESENTED IN THIS ENTRY. THIS WAS OBTAINED BY AVERAGING THE COORDINATES OF THE INDIVIDUAL STRUCTURES AND SUBJECTING THE RESULTING COORDINATES TO RESTRAINED MINIMIZATION. THE COORDINATES OF THE 21 INDIVIDUAL SA STRUCTURES ARE PRESENTED IN PROTEIN DATA BANK ENTRY 2BBN. THE LAST COLUMN IN THIS COORDINATE FILE REPRESENTS THE ATOMIC RMS DEVIATION OF THE INDIVIDUAL STRUCTURES ABOUT THE MEAN COORDINATE POSITIONS.
