MphR(A)/PmphR photochemical gene switch
Multi-Component SwitchThe MphR(A)/PmphR photochemical gene switch is an engineered bacterial transcription system in which the MphR(A)/PmphR regulatory module is coupled to a light-activatable erythromycin derivative. In E. coli, photoactivation of the erythromycin derivative enables ligand-dependent activation of transcription from the PmphR-controlled output.
