RESTRAINT MOLECULAR DYNAMICSIN ADDITION TO CLASSICAL NMR CONSTRAINTS THREE TYPES OF GLOBAL CONSTRAINTS WERE USED TO DEFINE THE GLOBAL STRUCTURE OF APO-CII IN THE APO-CII/SDS- MICELLE COMPLEX. SCRIPTS FOR THE GLOBAL STRUCTURE DETERMINATION HAVE BEEN WRITTEN AND ARE AVAILABLE UPON REQUEST. FINALLY, CNS WAS USED FOR THE FINAL MINIMIZATION.X-PLOR
