Comparative Genome Analysis Provides Molecular Evidence for Reclassification of the Photosynthetic Bacterium Rhodobacter sphaeroides EBL0706 as a Strain of Luteovulum azotoformans

Microorganisms, 2021
In this study, we conducted a genome-wide comparative analysis of a former Rhodobacter sphaeroides strain EBL0706, which is now recorded as Luteovulum sphaeroides EBL0706. The genome of EBL0706 was compared with that of Luteovulum azotoformans ATCC 17025,

The CheYs of Rhodobacter sphaeroides [PDF]

Journal of Biological Chemistry, 2006
The Escherichia coli two-component chemosensory pathway has been extensively studied, and its response regulator, CheY, has become a paradigm for response regulators. However, unlike E. coli, most chemotactic nonenteric bacteria have multiple CheY homologues.

Screening and engineering of high-activity promoter elements through transcriptomics and red fluorescent protein visualization in Rhodobacter sphaeroides

Synthetic and Systems Biotechnology, 2021
The versatile photosynthetic α-proteobacterium Rhodobacter sphaeroides, has recently been extensively engineered as a novel microbial cell factory (MCF) to produce pharmaceuticals, nutraceuticals, commodity chemicals and even hydrogen. However, there are

RsGDB, the Rhodobacter sphaeroides Genome Database [PDF]

Nucleic Acids Research, 1999
This report provides a summary of the sequencing project of the small chromosome (CII) of Rhodobacter sphaeroides 2.4.1(T),and introduces the first version of the genome database of this bacterium. The database organizes and describes diverse sets of biological information. The main role of the R.sphaeroides genome database (RsGDB) is to provide public

DNA repair mutants of Rhodobacter sphaeroides [PDF]

Journal of Bacteriology, 1995
The genome of the photosynthetic eubacterium Rhodobacter sphaeroides 2.4.1 comprises two chromosomes and five endogenous plasmids and has a 65% G+C base composition. Because of these characteristics of genome architecture, as well as the physiological advantages that allow this organism to live in sunlight when in an anaerobic environment, the ...

Analysis of the cbbXYZ operon in Rhodobacter sphaeroides [PDF]

Journal of Bacteriology, 1997
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.

Structural basis for the assembly and quinone transport mechanisms of the dimeric photosynthetic RC–LH1 supercomplex

Nature Communications, 2022
Bacterial photosynthesis reflects the early stages of the evolution of photosynthesis. Here, the authors present a systematic study of the cryo-EM structures of the dimeric light harvesting–reaction center complexes and assembly variants from Rhodobacter

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 ...

Spectroscopic characterization of reaction centers of the (M)Y210W mutant of the photosynthetic bacterium Rhodobacter sphaeroides [PDF]

, 1994
The tyrosine-(M)210 of the reaction center of Rhodobacter sphaeroides 2.4.1 has been changed to a tryptophan using site-directed mutagenesis. The reaction center of this mutant has been characterized by low-temperature absorption and fluorescence ...
