| DETAILS OF THE STRUCTURE DETERMINATION AND ALL STRUCTURAL
STATISTICS ARE GIVEN IN THE PAPER CITED ON THE 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 854 INTERPROTON DISTANCE RESTRAINTS DERIVED FROM
NOE MEASUREMENTS; 60 HYDROGEN-BONDING DISTANCE RESTRAINTS
FOR 30 HYDROGEN-BONDS IDENTIFIED ON THE BASIS OF THE NOE
AND AMIDE PROTON EXCHANGE DATA, AS WELL AS THE INITIAL
STRUCTURE CALCULATIONS; AND 54 PHI AND 51 PSI BACKBONE
TORSION ANGLE RESTRAINTS AND 39 CHI1 SIDE CHAIN TORSION
ANGLE RESTRAINTS DERIVED FROM COUPLING CONSTANTS AND NOE
DATA. THE LATTER ARE OBTAINED USING THE CONFORMATIONAL
GRID SEARCH PROGRAM STEREOSEARCH [NILGES, M., CLORE, G.M.
& GRONENBORN, A.M. (1990) BIOPOLYMERS 29, 813-822.
THE METHOD USED TO DETERMINE THE STRUCTURES IS THE HYBRID
METRIC MATRIX DISTANCE GEOMETRY-DYNAMICAL SIMULATED
ANNEALING METHOD [NILGES, M., CLORE, G.M. & GRONENBORN,
A.M. FEBS LETT. 229, 317-324 (1988)].
A TOTAL OF 60 STRUCTURES WERE CALCULATED. THE COORDINATES
OF THE RESTRAINED MINIMIZED STRUCTURE ARE PRESENTED IN
PROTEIN DATA BANK ENTRY 2GB1. THIS WAS OBTAINED BY
AVERAGING THE COORDINATES OF THE INDIVIDUAL STRUCTURES AND
SUBJECTING THE RESULTING COORDINATES TO RESTRAINED
MINIMIZATION. THE 60 STRUCTURES ARE PRESENTED IN PROTEIN
DATA BANK ENTRY 1GB1.
THE QUANTITY PRESENTED IN THE B VALUE FIELD (COLUMNS 61 -
66 OF THE ATOM AND HETATM RECORDS BELOW) REPRESENTS THE
ATOMIC RMS DEVIATION OF THE INDIVIDUAL STRUCTURES ABOUT THE
MEAN COORDINATE POSITIONS. | DISGEO |
