Additional NMR Experimental Information
Details	All spectrometers are equipped with a triple resonance (TXI) 5 mm probe with a z-axis pulse field gradient, and the 500 MHz spectrometer is equipped with a triple resonance cryo-probe. This structure was determined using pseudocontact shifts and residue dipolar couplings with all diamagnetic restraints
