Analysis of the interaction of FIR RRM1-RRM2 with Nbox peptides.
(a) Observed and fitted 1H, 15N-HMQC spectra of 41 μM FIR RRM1-RRM2 upon titration of FBP Nbox. Shaded area indicates the selection region of interest (ROI). (b) Observed and fitted 1H, 15N-HMQC spectra of 41 μM FIR RRM1-RRM2 upon titration of FBP3 Nbox. (c) Reported and fitted binding model parameters for the interaction of FIR RRM1-RRM2 with FBP and FBP3 Nbox.
