Method	Details	Software
	30 STRUCTURES WERE CALCULATED USING THE GEOMETRIC FORCE FIELD 'PARALLDHG.PRO'. THESE WERE SUBSEQUENTLY REFINED IN A 7 ANGSTROM SHELL OF WATER MOLECULES USING THE OPLS FORCE FIELD (TOPOPLSXX.PRO) AND AVERAGED. THIS AVERAGED STRUCTURE WAS ENERGY MINIMIZED USING AGAIN 'PARALLDHG.PRO'. THE PROGRAM WAS MODIFIED TO USE FLOATING CHIRALITY. CHIRAL-CENTER RESTRAINT (A**3) : 0.352	X-PLOR
