Bacteriorhodopsin is involved in halobacterial photoreception.
The bacterio-opsin gene was introduced into a "blind" Halobacterium salinarium mutant that (i) lacked all the four retinal proteins [bacteriorhodopsin (BR), halorhodopsin, and sensory rhodopsins (SRs) I and II] and the transducer protein for SRI and (ii) showed neither attractant response to long wavelength light nor repellent response to short wavelength light. The resulting transformed cells ...

متن کاملThe halobacterial insertion element ISH28.
A characteristic feature of the halophilic archaeon Halobacterium halobium (now termed Halobacterium salinarium) is the high genetic variability due to frequent transposition events. The organism contains a number of insertion sequences (ISH1, ISH2, ISH11, ISH23/ISH50, ISH24, ISH26, ISH27, ISH28, ISH SI, and ISH1.8) most of which have been isolated from the bacterioopsin {bop) gene region of pu...
متن کاملHalobacterial flagellins are sulfated glycoproteins.
The cell-surface glycoprotein of Halobacteria contains oligosaccharides of the type Glc4----1GlcA4----1GlcA4----1GlcA (where GlcA indicates glucuronic acid) with a sulfate group attached to each of the GlcA residues. We report here that in addition to this cell-surface glycoprotein, the halobacterial flagellar proteins (recently described by Alam, M., and Oesterhelt, D. (1984) J. Mol. Biol. 176...
متن کاملDrosophila timeless2 Is Required for Chromosome Stability and Circadian Photoreception
In Drosophila, there are two timeless paralogs, timeless1 (tim1) and timeless2 (tim2, or timeout). Phylogenetic analyses suggest that tim1 originated as a duplication of tim2 around the time of the Cambrian explosion. The function of tim1 as a canonical circadian component is well established, but the role of tim2 in the fly is poorly understood. Many organisms possess a single tim2-like gene t...
