Codon-optimized Halorhodopsin with His-tag

Halorhodopsin (HR) proteins are light-driven inward-directed chloride pumps from halobacteria. They are membrane-integral proteins of the rhodopsin superfamily that form a covalent bond with the carotenoid-derived chromophore all-trans retinal. Absorption of a photon with a defined optimal wavelength induces trans-cis isomerization of retinal, which triggers a catalytic photocycle of conformational changes in the protein, resulting in the net import of one chloride per photon into the cytoplasm.[1] And its electrophysiological properties have been characterized in Xenopus laevis oocytes.[2] We use it as our biodesalination driver which confers cyanobacteria the ability to absorb chloride to a significant degree.
