The light-driven proton pump proteorhodopsin enhances bacterial survival tough times
Some microorganisms contain proteins that can interact with light and convert it into energy for growth and survival, or into sensory information that guides cells towards or away from light. The simplest energy-harvesting photoproteins are the rhodopsins, which consist of a single, membrane-emb...

| description | Some microorganisms contain proteins that can interact with
light and convert it into energy for growth and survival, or into
sensory information that guides cells towards or away from light.
The simplest energy-harvesting photoproteins are the rhodopsins,
which consist of a single, membrane-embedded protein covalently
bound to the chromophore retinal (a light-sensitive pigment) [1].
One class of archaeal photoproteins (called bacteriorhodopsin) was
shown to function as a light-driven proton pump, generating
biochemical energy from light [2,3]. For many years, these lightdriven
proton pumps were thought to be found only in relatively
obscure Archaea living in high salinity. |
