CRISPR/Cas9-deaminase enables robust base editing in Rhodobacter sphaeroides 2.4.1

Microbial Cell Factories, 2020
Background CRISPR/Cas9 systems have been repurposed as canonical genome editing tools in a variety of species, but no application for the model strain Rhodobacter sphaeroides 2.4.1 was unveiled.

The PhyR homolog RSP_1274 of Rhodobacter sphaeroides is involved in defense of membrane stress and has a moderate effect on RpoE (RSP_1092) activity

BMC Microbiology, 2018
Background A major role of the PhyR-NepR-σ(EcfG) cascade in the general stress response was demonstrated for some bacterial species and considered as conserved in Alphaproteobacteria.

Rhodobacter sphaeroides: complexity in chemotactic signalling

Trends in Microbiology, 2008
Most bacteria have much more complex chemosensory systems than those of the extensively studied Escherichia coli. Rhodobacter sphaeroides, for example, has multiple homologues of the E. coli chemosensory proteins. The roles of these homologues have been extensively investigated using a combination of deletion, subcellular localization and ...

RNase E cleavage shapes the transcriptome of Rhodobacter sphaeroides and strongly impacts phototrophic growth

Life Science Alliance, 2018
This study identifies the cleavage sites of the endoribonuclease RNase E in the Rhodobacter sphaeroides transcriptome and demonstrates its effect on oxidative stress resistance and phototrophic growth.

DegS and RseP homologous proteases are involved in singlet oxygen dependent activation of RpoE in Rhodobacter sphaeroides. [PDF]

PLoS ONE, 2013
Singlet oxygen ((1)O2) is the main agent of photooxidative stress and is generated by photosensitizers as (bacterio)chlorophylls. It leads to the damage of cellular macromolecules and therefore photosynthetic organisms have to mount an adaptive response ...

Potassium chemotaxis in Rhodobacter sphaeroides

FEBS Letters, 1990
The addition of potassium to Rhodobacter sphaeroides in the absence of magnesium increased the membrane potential, as measured by the carotenoid bandshift. In the presence of magnesium, potassium decreased the membrane potential. Potassium stimulated the mean population swimming speed by 33% and 48% in the presence or absence of magnesium, respectively.

Efficient Cas9-based genome editing of Rhodobacter sphaeroides for metabolic engineering

Microbial Cell Factories, 2019
Background Rhodobacter sphaeroides is a metabolically versatile bacterium that serves as a model for analysis of photosynthesis, hydrogen production and terpene biosynthesis. The elimination of by-products formation, such as poly-β-hydroxybutyrate (PHB),
