bacteriorhodopsin

A light-driven proton-pumping protein (248 residues, 26 kD), similar to rhodopsin, found in 'purple patches' in the cytoplasmic membrane of the bacterium Halobacterium halobium . It is composed of 7 transmembrane helices, and contains the light-absorbing chromophore, retinal. Light absorption maxima: 568nm (light-adapted); 558nm (dark-adapted). Each photon results in the movement of 2 protons from cytoplasmic to extracellular sides of the membran … ...

Bacteriorhodopsin

Bacteriorhodopsin is a protein used by Archaea, the most notable one being Halobacteria. It acts as a proton pump; that is, it captures light energy and uses it to move protons across the membrane out of the cell. The resulting proton gradient is subsequently converted into chemical energy. == Structure == Bacteriorhodopsin is an integral membrane...

bacteriorhodopsin

The basis of a simple photosynthetic system that provides some species of archaea, known as halobacteria, with chemical energy. Interestingly, bacteriorhodopsin is chemically very similar to the light-senstive pigment rhodopsin, found in the vertebrate retina.
