15N/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.
