Figure 4.
1H-15N HSQC NMR spectra for COR15A WT and mutants in the presence of 20% TFE. The blue peaks depict the WT protein, the red peaks indicate the single mutant G68A and the quadruple 4GtoA mutant is represented by the black peaks. The peaks are labelled with the residue-specific assignments for the WT protein and the two circled unlabeled peaks at the bottom left represent the G68A residue in the single and quadruple mutant.
