SIMULATED ANNEALING FOR 48 PS AT 2000K FOLLOWED BY A SLOW COOL TO 50K STRUCTURE BASED ON 834 RESTRAINTS: 140 LONG-RANGE RESTRAINTS, 30 PHI ANGLE RESTRAINTS, AND 14 CHI-1 ANGLE RESTRAINTS. 83 OF THE LONG-RANGE NOES (59%) WERE DETERMINED TO ARISE FROM INTER-MONOMER CORRELATIONS BY COMPUTATIONAL METHODS. THE OTHER NOES WERE TREATED USING A WEIGHTING FUNCTION DEVELOPED FOR SYMMMETRIC HOMODIMERS THAT ALLOWS EACH NOE TO ARISE FROM EITHER AN INTRA- OR INTER- MONOMER CORRELATIONS AS DESCRIBED BY NILGES, M. PROTEINS (1993) 17:297- 309. SYMMETRY TERMS WERE EMPLOYED FOR C-ALPHA CARBONS ONLY. SEE JACS(1998)120: 1138-1145 FOR MORE DETAILS. 1
