Figure 4From: Quantitative investigation of the affinity of human respiratory syncytial virus phosphoprotein C-terminus binding to nucleocapsid proteinBackbone amide resonances of 15N-labeled N(31-252) from two-dimensional [ 15N, 1H] TROSY spectra. Blue, no ligand. Red, peptide ligand. The concentration of N(31-252) was 0.15 mM. (A) 2 mM Asp-Phe. (B) 0.3 mM D(pS)DNDL(pS)LEDF.Back to article page
