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. |
