Details 50 INITIAL RANDOM STRUCTURES WERE CALCULATED USING SIMULATED ANNEALING IN DYANA SOFTWARE. REFINEMENT WAS DONE WITH 500 STEPS RESTRAINED MINIMIZATION, 35PS MD IN VACUO AT 300K FOR EQUILIBRATION, 200PS MD UNDER NMR RESTRAINTS, AND 750PS CONJUGATED GRADIENT EM USING DISCOVER MODULE OF MSI SOFTWARE.

Additional NMR Experimental Information
1 THIS STRUCTURE WAS DETERMINED USING STANDARD 2D HOMONUCLEAR TECHNIQUES. NOESY EXPERIMENTS WITH MIXING TIMES FROM 80MS TO 800MS WERE RECORDED IN ORDER TO DEFINE THE BEST CONDITIONS IN ORDER TO AVOID SPIN DIFFUSION.
