NMR Refinement
Method	Details	Software
molecular dynamics	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 0% 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.	CYANA

NMR Ensemble Information
Conformer Selection Criteria	target function
Conformers Calculated Total Number	100
Conformers Submitted Total Number	20
Representative Model	1 (closest to the average)

Additional NMR Experimental Information
Details	The sample was not very stable and multiple samples were made (same conditions) to collect the data.
