SELECTIVE F O R M A T I O N OF BACTERIO-OPSIN TRIMERS BY CHEMICAL CROSSLINKING OF PURPLE MEMBRANE Hans-Georg DELLWEG and Manfred SUMPER
The purple membrane ofHalobacterium halobium contains a single protein known as bacteriorhodopsin, which is composed of 1 mol retinal]mol bacterio-opsin [ 1 ]. The organization of the protein within each purple membrane sheet is that of an exact 2-dimensional crystal. X-ray and electron diffraction data have revealed that the bacteriorhodopsin in purple membrane is arranged as trimeric units in...
متن کاملBiogenesis of purple membrane: regulation of bacterio-opsin synthesis.
In the cell membrane of Halobacteria a photoreceptor protein, bacteriorhodopsin, forms a twodimensional hexagonal crystalline network within the lipid matrix [l-4] . This specialized domain of the membrane has been termed purple membrane [5,6]. Besides its attractiveness for bioenergetic studies, the purple membrane appears highly suited for studying the biogenesis of a membrane: Purple membran...

The bacterio-opsin (bop) gene of Halobacterium halobium R1 has been cloned with about 40 kilobases of flanking genomic sequence. The 40-kilobase segment is derived from the (G+C)-rich fraction of the chromosome and is not homologous to the major (pHH1) or minor endogenous covalently closed circular DNA species of H. halobium. A 5.1-kilobase Pst I fragment containing the bop gene was subcloned i...
