STRUCTURE BASED ON A TOTAL OF 1301 UNIQUE DISTANCE CONSTRAINTS (OBTAINED FROM
3095 NOE CROSSPEAKS), INCLUDING 374 INTRARESIDUE, 405 SHORT-RANGE, 228 MEDIUM
RANGE AND 294 LONG-RANGE CONSTRAINTS. DYANA 1.5 ANNEAL COMMAND (10000 STEPS)
USED TO GENERATE 40 CONFORMERS. 20 LOWEST TARGET FUNCTION STRUCTURES ANALYZED.
CONFORMER 4 CHOSEN FOR DEPOSITION AS CLOSEST TO MEAN COORDINATES OF THE
ENSEMBLE.

PHOSPHORYLATION (>95%) COULD BE MAINTAINED FOR 36 HR. TO OBTAIN SUFFICIENT S/N
IN 3D NOESY EXPERIMENTS, MULTIPLE (TYPICALLY 4) COMPLETE 3D DATASETS WERE
ACQUIRED ON FRESHLY PREPARED SAMPLES AND THEN COADDED TO YIELD HIGH-QUALITY
DATASETS FOR STRUCTURE DETERMINATION.
