Ammonium and methylammonium transport in Rhodobacter sphaeroides [PDF]
Journal of Bacteriology, 1987 Rhodobacter sphaeroides maintained intracellular ammonium pools of 1.1 to 2.6 mM during growth in several fixed nitrogen sources as well as during diazotrophic growth. Addition of 0.15 mM NH4+ to washed, nitrogen-free cell suspensions was followed by linear uptake of NH4+ from the medium and transient formation of intracellular pools of 0.9 to 1.5 mM ...

Features of Rhodobacter sphaeroides CcmFH [PDF]
Journal of Bacteriology, 2003 ABSTRACT In this study, the in vivo function and properties of two cytochrome c maturation proteins, CcmF and CcmH from Rhodobacter sphaeroides , were analyzed. Strains lacking CcmH or both CcmF and CcmH are unable to grow under anaerobic conditions where c ...

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%.

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.

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 ...

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.
