Spectrometer	Manufacturer	Model	Field Strength
1	Varian	INOVA	400
2	Bruker	AVANCE	600

NMR Refinement
Method	Details	Software
Rosetta refinement	RESIDUES 1-14 WERE HIGHLY DYNAMIC BASED ON SEPARATE SOLID-STATE NMR EXPERIMENTS AND WERE NOT INCLUDED IN THE FINAL MODELS	Rosetta

NMR Ensemble Information
Conformer Selection Criteria	target function
Conformers Calculated Total Number	10000
Conformers Submitted Total Number	5
Representative Model	1 (lowest energy)

Additional NMR Experimental Information
Details	WHILE INFORMATION FROM STEM MASS-PER-LENGTH MEASUREMENTS WAS USED TO ESTABLISH THE OVERALL 3-FOLD SYMMETRY OF THE SYSTEM, NO DETAILED EM MAP DENSITY WAS USED IN STRUCTURE REFINEMENT. THE REFINEMENT WAS BASED PRIMARILY ON THE SOLID-STATE NMR DATA
