Method	Details	Software
torsion angle dynamics	STRUCTURE DETERMINATION WAS PERFORMED ITERATIVELY USING CYANA (AUTOMATED NOESYASSIGNMENTS). A TOTAL OF 20 STRUCTURES OUT OF 100 WITH LOWEST TARGET FUNCTION FROM THE FINAL CYANA CALCULATION WERE TAKEN AND REFINED BY RESTRAINED MOLECULAR DYNAMICS/ENERGY REMARK IN EXPLICIT WATER (CNS) AFTER ADDING 10% TO THE UPPER BOUNDARY LIMIT. THE FINAL SET OF STRUCTURES CONTAINED NO DIHEDRAL VIOLATIONS GREATER THAN 2 DEGREE OR DISTANCE VIOLATIONS TOTAL THAT WERE GREATER THAN 0.05 ANGSTROM.	CYANA
