Additional NMR Experimental Information
Details15N/1H HSQC was used to Monitor (a) chemical shift perturbation upon complex formation to identify interaction interface, and (b) to identify backbone amide resonances that are significantly broadened due to their proximity to a paramagnetic spin label attached to its natural abundance homodimeric interaction partner.
