Additional NMR Experimental Information
Details	REPRESENTATIVE STRUCTURE, LEAST ENERGY. RESONANCE ASSIGNMENTS MADE USING TRIPLE RESONANCE EXPERIMENTS WERE FOLLOWED BY COLLATION OF DISTANCE RESTRAINTS USING NOESY EXPERIMENTS ON 15N,13C-LABELLED INT190 EXPERIMENTS ON 15N, 13C-LABELLED INT190. ONE BOND DIPOLAR COUPLINGS WERE MEASURED USING COUPLED HSQC AND TRIPLE RESONANCE EXPERIMENTS.
