Method	Details	Software
torsiona angle dynamics and simulated anealing	The structures were determined using multi-dimension hetero-nuclear NMR spectroscopy. The constraints consist of NOE, diheadral, J-coupling, chemical shift, conformational data base as well as two setsof dipolar couplings measured from two different alignment media.	xplor-nih
