Pconst.-SRⅡ-HtrⅡ-EnvZ-Pompc-taRNA-DT-Pconst.-HHR-GFP-DT

Halophilic archaea, such as Halobacterium salinarum and Natronobacterium pharaonis (N. pharaonis) are known to show phototaxis by the illumination of light by using receptors called sensory rhodopsin I and II (SRI and SRII). The SR proteins are seven-transmembrane retinylidene photoreceptors, which transmits blue light signal (λmax 487 nm) to their corresponding transducers HtrI and HtrII respectively. This two-component system regulates cells’ flagellar motors for phototaxis (Ref. 1, 2).

In dark, Sensory rhodopsin phospholylates OmpR response regulator and OmpR response regulator activates P_ompC, so taRNA will be expressed. When taRNA expresses, it will repress HHR's activity and RBS will not be exposed and GFP expression willl not be observed. In blue light, taRNA will not be expressed, therefore HHR causes auto cleavage and RBS is exposed, so GFP eill expresse.
