Blue-light photoreceptor

UniProtKB accession:  O34627

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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.
