Deletion of sll1541 in Synechocystis sp. Strain PCC 6803 Allows Formation of a Far-Red-Shifted holo-Proteorhodopsin In Vivo
Abstract
(encoding SynACO) as the essential gene for retinal synthesis. Multiple pathways for retinal degradation presumably exist. These results have allowed us to construct a strain that expresses a light-dependent proton pump with an action spectrum extending beyond 700 nm. The availability of this strain will be important for further work aimed at increasing the overall efficiency of oxygenic photosynthesis.
