bifunctional optogenetic switch
Multi-Component SwitchBOS is a bifunctional optogenetic transcriptional control system developed in Escherichia coli by combining the light-inducible transcriptional regulator LEVI mutant with the chemical-inducible repressor LacI. It enables blue-light-responsive regulation of target genes and has been applied to metabolic engineering for shikimic acid and l-valine production.
