(A) Infrared fluorescence of E. coli colonies expressing the fusion proteins before and after irradiation (480±15 nm excitation). (B) Predicted structure of miniSOG by the Swiss-Model structure homology-modeling server [52]. (C) Mutations introduced into miniSOG compared to its parent. Numbers in bracket are based on miniSOG protein sequence. (D) Normalized absorbance (blue) and emission (red) spectra. (E) Degradation of ADPA by illumination of miniSOG (red) or free FMN (blue).
