A pigmented membrane protein found in extremely halophilic archaea of the genus Halobacterium that converts light energy to chemical energy and is structurally similar to rhodopsin.

Together with structural analysis of plant light-harvesting complex, (25) this analysis of bacteriorhodopsin demonstrated the usefulness of our cryo-EMs for high-resolution structural analyses.
In another innovative approach, artificially prepared vesicles known as liposomes were assembled on a quartz crystal microbalance via layer-by-layer growth using the membrane protein bacteriorhodopsin as a binding reagent.
While much structural knowledge has been gained about membrane proteins including GPCRs through innovative techniques such as atomic force microscopy, where the cytoplasmic conformational space of bacteriorhodopsin has been sampled (111), computational approaches are increasingly successful and considered full partners to experimental approaches (112).

Another tact is to design synthetic membrane systems that copy plants' ability to convert light into the biochemical energy of ATE In one version, developed by the CSIRO group, a purple membrane protein called bacteriorhodopsin, from a type of bacterium, is tethered onto a solid surface to which a lipid bilayer is anchored.
