Pconst.-SRⅡ-HtrⅡ-EnvZ-Pompc-HHR-GFP-DT-Pconst.-taRNA-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 PompC, so HHR will be expressed. Since HHR contains GFP gene and RBS, GFP will express as long as HHR causes self cleavage. However, taRNA represses HHR's activity, therefore GFP’s RBS will not be exposed and GFP will not expressed.
