as follows: 500 ml 230 medium 100 reciprocating movements per min for 5 days at Low purple membrane production is observed under conditions of sufficient aeration: cells were grown in Erlenmeyer flasks containing only 90 ml medium under otherwise in the presence of mM nicotine yielded cells with ml medium) or (90 ml of bacteria-opsin, respectively (‘nicotine [7 ] Basal salt solution contained l...
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...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولStudies on the biosynthesis of bacterio-opsin. Demonstration of the existence of protein species structurally related to bacterio-opsin.
1. The kinetics of processing newly synthesized bacterio-opsin from the non-crystalline state within the brown membrane to the crystalline state within the purple membrane was followed by pulse-chase experiments. 2. Biosynthesis of bacterio-opsin was found to be highly resistant to RNA-synthesis inhibitors like rifampicin and ethidium bromide. In the presence of ethidium bromide, only five prot...
متن کاملBacterio-opsin mutants of Halobacterium halobium.
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...
