Function

PHOT_BACSU Exhibits the same spectroscopical features and blue-light induced photochemistry as plants phototropins, with the reversible formation of a blue-shifted photoproduct, assigned to an FMN-cysteine thiol adduct. Although it is a positive regulator in the activation of the environmental signaling branch of the general stress transcription factor sigma-B, its precise role is undetermined.^[1]
