WebSensory rhodopsin II (SRII, also known as phoborhodopsin) is a negative phototaxis receptor in haloarchaea, including H. salinarum and Natronomonas pharaonis. Those are called Hs … Webthought that light excitation of sensory rhodopsin II from Natronobacterium pharaonis (SRII) in complex with its transdu-cer (HtrII) induces an outward movement of its helix F (ref. 6), which in turn triggers a rotation of TM2 (ref. 7). It is unclear how this TM2 transition is converted into a cellular signal. Here we
