Definitions
American Heritage® Dictionary of the English Language, Fourth Edition
- n. A purple pigment similar to rhodopsin occurring in the cell membranes of bacteria of the genus Halobacterium that converts sunlight directly into chemical energy.
Wiktionary
- n. biochemistry Any of several related purple photosynthetic proteins, found in halobacteria, that act as proton pumps.
Examples
“One class of archaeal photoproteins (called bacteriorhodopsin) was shown to function as a light-driven proton pump, generating biochemical energy from light”
“They have opsins that they use for both light detection (sensory rhodopsin-I and sensory rhodopsin-II) *and* photosynthesis without chlorophyll (bacteriorhodopsin and halorhodopsin).”
“Once again we have a one step “cascade”, and a light spot based on this bacteriorhodopsin is something eminently evolvable.”
“Opsin is a very old molecule; bacteria have their own version, bacteriorhodopsin, which in its simple form is a single molecule that pumps ions across a membrane Spudich 1998.”
“The other interesting finding is that the genome of H. walsbyi encodes 2 bacteriorhodopsin proteins.”
“My mother was more interested in the _Deinococcus radiodurans_ and bacteriorhodopsin experiments.”
“Henderson's atomic model of bacteriorhodopsin, or John Walker's mitochondrial ATPase structure, have required sustained efforts lasting many years and could never have been solved if we had had to depend on short-term grants.”
The Medical Research Council Laboratory of Molecular Biology
“Our bacteriorhodopsin crystals were found to diffract X-rays, but to be too small and too disordered for a structural analysis.”
“Frustrated from the lack of the final success with bacteriorhodopsin, I tried to crystallize several other membrane proteins, mainly photosynthetic ones.”
“With Oesterhelt's help I started the experiments, and already four weeks later we obtained a new two-dimensional membrane crystal of bacteriorhodopsin.”
