Complexes of Rhodobacter sphaeroides and Rhodobacter capsulatus
Photosynthetic bacteria offer excellent experimental opportunities to explore both the structure and function of the ubiquinol-cytochrome c oxidoreductase (bcl complex). In both Rhodobacter sphaeroides and Rhodobaeter capsulatus, the bCl complex functions in both the aerobic respiratory chain and as an essential component of the photosynthetic electron transport chain. Because the bc~ complex i...
متن کاملOsmoregulation in Rhodobacter sphaeroides.
Betaine (N,N,N-trimethylglycine) functioned most effectively as an osmoprotectant in osmotically stressed Rhodobacter sphaeroides cells during aerobic growth in the dark and during anaerobic growth in the light. The presence of the amino acids L-glutamate, L-alanine, or L-proline in the growth medium did not result in a significant increase in the growth rate at increased osmotic strengths. The...
متن کاملThe Lipoprotein and Peptidoglycan of Rhodobacter sphaeroides
The lipoprotein-peptidoglycan complex (rigid layer) from Rhodobacter sphaeroides was iso lated. Treatm ent of the complex with N.O-diacetyl-muramidase cleaved off from the rigid layer the lipoprotein moiety with covalently bound peptidoglycan-fragments. The lipoprotein with the bound fragments showed a broad single band (M r about 19,000) on SDS-polyacrylamide gels and had an isoelectric point...
متن کاملThe photosynthetic apparatus of Rhodobacter sphaeroides.
Functional and ultrastructural studies have indicated that the components of the photosynthetic apparatus of Rhodobacter sphaeroides are highly organized. This organization favors rapid electron transfer that is unimpeded by reactant diffusion. The light-harvesting complexes only partially surround the photochemical reaction center, which ensures an efficient shuttling of quinones between the p...
متن کاملPostgenomic adventures with Rhodobacter sphaeroides.
This review describes some of the recent highlights taken from the studies of Rhodobacter sphaeroides 2.4.1. The review is not intended to be comprehensive, but to reflect the bias of the authors as to how the availability of a sequenced and annotated genome, a gene-chip, and proteomic profile as well as comparative genomic analyses can direct the progress of future research in this system.
