Abstract

Bacteriorhodopsin (BR) is an integral membrane protein in Halobacteria which uses the sunlight to generate a proton gradient across the cell membrane. Proton gradients play a fundamental role in energy transduction. They are found in photosynthesis as well as in the respiratory chain. According to Mitchell’s chemiosmotic theory, a proton gradient can be utilized by a proton consumer (H+-ATP-synthase) to produce ATP (adenosine-triphosphate), the universal storage device for the energy required in every metabolic process of life.
