Cardiolipin Alters Rhodobacter sphaeroides Cell Shape by Affecting Peptidoglycan Precursor Biosynthesis

mBio, 2019
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%.

Supplementing in the diet of lactating Holstein cows may naturally produce coenzyme Q10-enriched milk [PDF]

Asian-Australasian Journal of Animal Sciences, 2018
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 ...

Phosphotransfer in Rhodobacter sphaeroides Chemotaxis

Journal of Molecular Biology, 2002
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.

Rhodobacter azotoformans LPS (RAP99-LPS) Is a TLR4 Agonist That Inhibits Lung Metastasis and Enhances TLR3-Mediated Chemokine Expression

Frontiers in Immunology, 2021
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.

The architecture of Rhodobacter sphaeroides chromatophores

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2014
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.

Split histidine kinases enable ultrasensitivity and bistability in two-component signaling networks [PDF]

, 2012
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.

Feedback Control Architecture and the Bacterial Chemotaxis Network [PDF]

, 2011
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.

Taxogenomics Resolves Conflict in the Genus Rhodobacter: A Two and Half Decades Pending Thought to Reclassify the Genus Rhodobacter

Frontiers in Microbiology, 2019
The genus Rhodobacter is taxonomically well studied, and some members are model organisms. However, this genus is comprised of a heterogeneous group of members.
