Cardiolipin (CL) is an anionic phospholipid that plays an important role in regulating protein biochemistry in bacteria and mitochondria. Deleting the CL synthase gene (Δcls) in Rhodobacter sphaeroides depletes CL and decreases cell length by 20%.

The architecture of Rhodobacter sphaeroides chromatophores
The chromatophores of Rhodobacter (Rb.) sphaeroides represent a minimal bio-energetic system, which efficiently converts light energy into usable chemical energy. Despite extensive studies, several issues pertaining to the morphology and molecular architecture of this elemental energy conversion system remain controversial or unknown.

Analysis of the cbbXYZ operon in Rhodobacter sphaeroides [PDF]
Three genes, cbbX, cbbY, and cbbZ were found downstream from the form I ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO) genes of Rhodobacter sphaeroides. As in chemoautotrophic bacteria, cbbZ was shown to encode phosphoglycolate phosphatase (PGP), whereas the identities of cbbX and cbbY are not known.

Supplementing in the diet of lactating Holstein cows may naturally produce coenzyme Q10-enriched milk [PDF]
Objective To examine the effects of Rhodobacter sphaeroides (R. sphaeroides) supplementation as a direct-fed microbial (DFM) on rumen fermentation in dairy cows and on coenzyme Q10 (CoQ10) transition into milk, an in vitro rumen simulation batch culture ...

Split histidine kinases enable ultrasensitivity and bistability in two-component signaling networks [PDF]
Bacteria sense and respond to their environment through signaling cascades generally referred to as two-component signaling networks. These networks comprise histidine kinases and their cognate response regulators.

The lipopolysaccharides (LPSs) of Rhodobacter are reported to be TLR4 antagonists. Accordingly, the extract of Rhodobacter azotoformans (RAP99) is used as a health supplement for humans and animals in Japan to regulate immune responses in vivo.

Phosphotransfer in Rhodobacter sphaeroides Chemotaxis
The two-component sensing system controlling bacterial chemotaxis is one of the best studied in biology. Rhodobacter sphaeroides has a complex chemosensory pathway comprising two histidine protein kinases (CheAs) and eight downstream response regulators (six CheYs and two CheBs) rather than the single copies of each as in Escherichia coli.

Feedback Control Architecture and the Bacterial Chemotaxis Network [PDF]
This paper investigates the chemotaxis behavior of the bacterium R. sphaeroides. We review the results of a recent study comparing different possible mathematical models of this bacterium's chemotaxis decision mechanisms.
