simulated annealing with torsion angle dynamics (DYANA) followed by molecular dynamics (AMBER)	1016 NOE-derived restraints: 120 intra, 346 sequential, 268 medium and 282 long-range restraints. The first 5 residues (S5-G9) show only intra-residue and sequential NOE connectivites and were not included in our structural calculations.	VNMR
