Method	Details	Software
DGSA-distance geometry simulated annealing	STRUCTURE DETERMINATION WAS PERFORMED ITERATIVELY USING CYANA (AUTOMATED NOESY ASSIGNMENTS). 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 MINIMIZATION IN EXPLICIT WATER (CNS) AFTER ADDING 5% TO THE UPPER BOUNDARY LIMIT OF THE DISTANCE RESTRAINTS AND THE VDW LIMIT TO THE LOWER RESTRAINT. PARAM19 WAS USED FOR THE WATER REFINEMENT CALCULATIONS.	Sparky
