FIG 5.
Light-dependent change of absorbance spectrum of LitR recombinant protein. (A) Absorbance spectrum of the recombinant protein LitR. The absorbance spectrum of LitR was recorded after the sample was illuminated for 60 s and 180 s using LED lamps, UV-A (λmax = 365 nm) at 0.06 μmol · s−1 · m−2, on the sample. (B) Dark-state recovery measured at 60 and 120 min. (C) Effects of illumination of various wavelengths of light. The type of light reducing the absorbance spectrum at 340 nm of LitR was examined. Illumination time was 180 s.
