The present invention relates to a method for extracting bacterio-rhodopsin from bacteria by means of a multi-step purification method.

The invention relates to a method for the linker-free covalent coupling of bakteriorhodopsin in purple membrane form.

Two methods for bacteriorhodopsin incorporation have been developed: (a) formation of planar membrane from a mixture of decane solution

The light sensitive material is preferably bacteriorhodopsin, which is immobilised by embedding or optionally cross-linking in a suitable matrix material.

Photoreceptive proteins, such as bacteriorhodopsin (BR), are able to convert light directly into a signal.

La3+ ions were shown to inhibit operation of those bacteriorhodopsin which pump out H+ ions from the La3+-containing compartment.

., Direct measurement of electric current generation by cytochrome oxidase, H+-ATPase and bacteriorhodopsin.

The researchers injected bacteriorhodopsin crystals into the X-ray beam with a special injector.

Researchers around the world use the protein bacteriorhodopsin to investigate such ultrafast processes.

Preferably, the biopolymer is a liquid crystal polypeptide, such as ferroelectric liquid crystal poly(η-methyl-L-glutamate), and the photochromic compound is bacteriorhodopsin.

Direct measurement of electric current generation by cytochrome oxidase, H+-ATPase and bacteriorhodopsin. –Nature.

Direct measurement of electric current generation by cytochrome oxidase, H+-ATPase and bacteriorhodopsin.

Bacteriorhodopsin is embedded in purple membrane and is a common protein for research in the biosciences.

Bacteriorhodopsin is a protein that absorbs light and transports protons across cell membranes—a key function of biological systems.

The present invention provides a solid material comprising an immobilized mixture of two or more proteorhodopsins, two or more bacteriorhodopsins, or one or more bacteriorhodopsin and one or more proteorhodopsins.
