THE STRUCTURES WERE CALCULATED USING THE SIMULATED
ANNEALING PROTOCOL OF NILGES ET AL. (1988) FEBS LETT. 229,
129-136 USING THE PROGRAM X-PLOR 3.1 (BRUNGER) MODIFIED TO
INCORPORATE COUPLING CONSTANT (GARRETT ET AL. (1984) J.
MAGN. RESON. SERIES B 104, 99-103) AND CARBON CHEMICAL
SHIFT (KUSZEWSKI ET AL. (1995) J. MAGN. RESON. SERIES B
106, 92-96) RESTRAINTS, AND T1/T2 RESTRAINTS
(TJANDRA ET AL. NATURE STRUCT. BIOL. 4, 443-449, 1997).
IN THIS ENTRY THE LAST COLUMN REPRESENTS THE AVERAGE RMS
DIFFERENCE BETWEEN THE INDIVIDUAL SIMULATED ANNEALING
STRUCTURES AND THE MEAN COORDINATE POSITIONS. THE LAST
COLUMN IN THE INDIVIDUAL SA STRUCTURES HAS NO MEANING.
BEST FITTING TO GENERATE THE AVERAGE STRUCTURE IS WITH
RESPECT TO RESIDUES 1 - 246 (RESIDUES 250 - 259 ARE
DISORDERED IN SOLUTION).
THE DIFFUSION AXIS IS REPRESENTED BY A LINE CONNECTING THE
