SIMULATED ANNEALING, MOLECULAR DYNAMICS	NOE ASSIGNMENT WITH CYANA, REFINEMENT BY SIMULATED ANNEALING IN XPLOR-NIH USING NOE RESTRAINTS AND H-BOND RESTRAINTS FROM H/D EXCHANGE DATA. WATER REFINEMENT IN CNS. THE C-TERMINAL TAIL HAS BEEN TRUNCATED PAST RESIDUE 134 BECAUSE OF FLEXIBILITY AND LACK OF STRUCTURE IN THIS REGION. THIS IS INDICATED (A) BY A LACK OF NOE RESTRAINTS PAST RESIDUE 132 AND (B) BY 15N T1, T2 AND HETERONCULEAR NOE EXPERIMENTS RESIDUE 131 ONWARDS.	CNS
