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

Sparse bayesian step-filtering for high-throughput analysis of molecular machine dynamics [PDF]
Nature has evolved many molecular machines such as kinesin, myosin, and the rotary flagellar motor powered by an ion current from the mitochondria. Direct observation of the step-like motion of these machines with time series from novel experimental ...

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

Rhodobacter sphaeroides: complexity in chemotactic signalling
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 ...

Phenotypic characterisation and genetic complementation of dimethylsulfoxide respiratory mutants of Rhodobacter sphaeroides and Rhodobacter capsulatus [PDF]
Two chlorate resistant mutants of Rhodobacter sphaeroides were isolated which were deficient in dimethylsulfoxide reductase activity. Immunoblotting experiments showed that the phenotype of these mutants and that of Rhodobacter capsulatus strain DK9, a ...

Physiological and Mechanistic Studies of Phototrophic Fe(II) Oxidation in Purple Non-sulfur Bacteria [PDF]
Phototrophic Fe(II)-oxidizing bacteria use electrons from ferrous iron [Fe(II)] and energy from light to drive reductive CO₂ fixation. This metabolism is thought to be ancient in origin, and plays an important role in environmental iron cycling. It has

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