Figure 2. Absorption spectra and titration curves of GR and its mutants.

Figure 2

Insets show photos of purified WT and mutant GR in 50 mM Tris (pH 7), 150 mM NaCl, and 0.02% DDM. The pH titration curves indicate the pH dependence of the absorption maxima of broad spectral range. The pKa values are shown in the table 1.
