1 H-15 N heteronuclear single quantum coherence spectrum (HSQC) of full-length Ca2+ -S100A4 at 600 MHz. Black: S100A4 bound to the MIIA1893-1923 peptide (0.25 mM S100A4 subunit and 0.75 mM MIIA1893-1923). Green: Following the addition of 42 μM MIIA1893-1923-Cys-Proxyl peptide. Residues exhibiting a significant reduction in intensity are labeled.
