Additional NMR Experimental Information
Details	THE STRUCTURE WAS DETERMINED USING 15N, 13C AND 2D LABELED SAMPLES. DIFFERENT LABELLED SPECIES WERE MIXED IN DIFFERENT EXPERIMENTS. TRIPLE RESONANCE EXPERIMENTS COULD NOT BE USED DUE TO THE SIZE OF THE COMPLEX; TROSY WAS NOT AVAILABLE WHEN MOST OF THE ASSIGNMENT WAS COMPLETED.
