Sensory rhodopsin II (SRII) with HtrII & Tsr, sensitive to blue-green light

Sensory Rhodopsin II have been fused with HtrII with the a linker peptide, only the membrane-proximal cytoplasmic domain have been kept, while the cytoplasmic domains have been replaced by that of Tsr. Once the fusion protein was triggered, the histidine kinase (CheA) will be up regulated, leading to longer tumbling period(Negative phototaxis), sensitive to blue-green light, with sensing spectra covering from 400-500 nm. We used it for sensing blur-green light to achieve phototaxis and switch for downstream gene expression.
