Archeal light receptor fused to bacterial chemotaxis transducer
Biological Background
Fusion of the Natronobacterium pharaonis Np seven-transmembrane retinylidene photoreceptor sensory rhodopsins II NpSRII and their cognate transducer HtrII to the cytoplasmic domain of the chemotaxis transducer EcTsr of Escherichia coli [1].
Rhodopsins are photoreactive, membrane-embedded proteins, which are found not only in archaea, but in eubacteria and microbes as well. In Natronobacterium pharaonis, the NpSRII contains a domain of seven membrane-spanning helices, which carry out two distinct functions: Firstly, they serve as photo-inducible ion-pumps and secondly, as actors in the chemotaxis signaling network [1].
All-trans retinal is needed for NpSRII to change it's conformation into an active light absorbing pigment. It can either be added to the growth media or produced by the organism. Phototactic stimuli can be delivered through a light pulse at 500 nm.
Design
