Bacteriorhodopsin is an integral membrane protein usually found in two-dimensional crystalline patches known as "purple membrane", which can occupy up to nearly 50% of the surface area of the archaeal cell. There is a much greater density per unit membrane area of
photochemical reaction centres in an ion-pumping rhodopsin
‘purple membrane’ (~270 nmol/m^2, 135 nmol/m^2 if half
of the membrane is purple membrane, allowing room for
F0F1-type ATP synthetases, respiratory enzymes and solute
transporters) than in the thylakoid membrane of an oxygenic
phototroph (~5 nmol/m^2 for each photosystem for a sun-adapted or acclimated vascular plant). See BNID 105045 |
