Fig. 2: Apparent association constants Ka for the binding of Hofmeister ions to individual amides in barnase.
From: Interactions between the protein barnase and co-solutes studied by NMR
Histograms are (a) thiocyanate, (b) chloride, (c) sulfate, and show the fitted Ka for binding to amide proton, amide nitrogen and backbone carbonyl (from the previous residue), together with the mean. Residues for which no Ka could be fitted are shown with black bars. Ka values are indicated on the structures on the right, first as individual H/N/C and then as the mean. Residues for which there is no data are shown as blue, and increasingly strong affinities are shown as redder colors and thicker tubes. Residue numbering can be found in Fig. S4.
