WebChemoreceptors and sensory rhodopsin-based photoreceptors are involved in chemo- and phototaxis, but they can also perform other functions [10,11,27,28]. They form higher-order assemblies composed of trimers-of-dimers of the receptor proteins in complex with the histidine kinase CheA and accessory proteins [ 27 , 29 ]; the activity of CheA is regulated … WebRetinylidene proteins, or rhodopsins in a broad sense, are proteins that use retinal as a chromophore for light reception. They are the molecular basis for a variety of light-sensing systems from phototaxis in flagellates to eyesight in animals. [1] Retinylidene proteins include all forms of opsin and rhodopsin (in the broad sense).
