Binding of 6-nt RNA oligomers to individual RBDs of Msi1. Overlays of the 15N-HSQC spectra sections of RBD1 (red), and RBD1 in the presence of 0.2 (orange), 0.5 (green), 1.0 (blue) and 1.2 (purple) equivalents of 6-nt RNA oligomers: (A) r(UAGGUA) (numb6-1); (B) r(GGUAGU) (numb6-2); (C) r(UAGUAG) (numb6-3); (D) r(GUAGUU) (numb6-4); (E) r(AGUUUU) (numb6-5) and (F) r(GUUUUA) (numb6-6). Overlays of the 15N-HSQC spectra sections of RBD2 (red) and RBD2 in the presence of 0.2 (orange), 0.5 (green), 1.0 (blue) and 1.2 (purple) equivalents of 6-nt RNA oligomers: (G) numb6-1; (H) numb6-2; (I) numb6-3; (J) numb6-4; (K) numb6-5 and (L) numb6-6. (M) The chemical shift changes, Δδ, were obtained by subtracting the chemical shifts of Msi1 backbone 1HN for the free protein from the chemical shifts of Msi1 backbone 1HN in the complex (Msi1:RNA oligomer = 1:1).
