YF1/FixJ system
Multi-Component SwitchThe YF1/FixJ system is a blue light-repressible multi-component optogenetic switch evaluated for transcriptional control in the cyanobacterium Synechococcus sp. PCC 7002. In the cited PCC 7002 study, it was tested as a heterologously expressed light-input gene regulation system and showed limited performance, with a reported maximum dynamic range of 1.5-fold.
