NMR Refinement
Method	Details	Software
torsion angle 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. Disulfide bond restraints were identified by mass spectrometer and are included in the "NOE" file.	CNS
