Figure 2. pH-dependent, reversible color tuning of GmKate.

Figure 2

Absorbance spectra of GmKate, mKateS158A and mKate at pH 7.4 and pH 10.0 are shown. The plots were scaled at the same protein concentration. Measurements were carried out at 25°C. Buffers with different pH were exchanged by using fast desalting columns.
