Examination of the Global Regulon of CsrA in Xanthomonas citri subsp. citri Using Quantitative Proteomics and Other Approaches

Molecular Plant-Microbe Interactions, 2021
The RNA-binding protein CsrA is a global posttranscriptional regulator and controls many physiological processes and virulence traits. Deletion of csrA caused loss of virulence, reduced motility and production of xanthan gum and substantial increase in ...

Utilizing Zirconium MOF‐functionalized Fiber Substrates Prepared by Molecular Layer Deposition for Toxic Gas Capture and Chemical Warfare Agent Degradation

Global Challenges, Volume 5, Issue 12, December 2021., 2021
Glass fibers coated with amorphous and crystalline amino‐functionalized Zr‐metal‐organic‐frameworks (Zr‐MOF) films show activity towards capturing NH3 and enabling the catalytic degradation of nerve agents. A novel, one‐step molecular layer deposition method is used for direct fiber coating. This indicates the potential of Zr‐MOF functionalized fibrous

RECX Interacts with Mitochondrial RECA to Maintain Mitochondrial Genome Stability [PDF]

Plant Physiology, 2018
The chloroplast and mitochondrial genomes are essential for photosynthesis and respiration, respectively. RECA and RECG, which are plant-specific homologs of the bacterial homologous recombination repair proteins RecA and RecG, maintain organelle genome stability by suppressing aberrant recombination between short dispersed repeats (SDRs) in the moss ...

Genetic organization of the lexA, recA and recX genes in Xanthomonas campestris [PDF]

FEMS Microbiology Letters, 2002
A gene cluster containing lexA, recA and recX genes was previously identified and characterized in Xanthomonas campestris pathovar citri (X. c. pv. citri). We have now cloned and sequenced the corresponding regions in the Xanthomonas campestris pv. campestris (X. c. pv. campestris) and Xanthomonas oryzae pathovar oryzae (X. o. pv.

Nucleoid‐associated Rok differentially affects chromosomal transformation on Bacillus subtilis recombination‐deficient cells

Environmental Microbiology, Volume 23, Issue 6, Page 3318-3331, June 2021., 2021
Summary Rok, a Bacillus subtilis nucleoid‐associated protein (NAP), negatively regulates competence development and silences xenogeneic genes. We show that rok inactivation increases rpoB482 natural intraspecies chromosomal transformation (CT) and plasmid transformation to a different extent.

The Reactivity of Multidentate Schiff Base Ligands Derived from Bi‐ and Terphenyl Polyamines towards M(II) (M=Ni, Cu, Zn, Cd) and M(III) (M=Co, Y, Lu)

European Journal of Inorganic Chemistry, Volume 2021, Issue 19, Page 1869-1889, May 20, 2021., 2021
Metal complexes of Schiff base ligands derived from a m‐terphenyl‐2,2’,2’’‐triamine were synthesized and studied by means of NMR spectroscopy and single‐crystal X‐ray diffraction analysis. The ligands were found to act as tetradentate, pentadentate, or hexadentate ligands, depending on the electronic properties of the substituents of the ligand, as ...

RecX is involved in antioxidant mechanisms of the radioresistant bacteriumDeinococcus radiodurans [PDF]

FEMS Microbiology Letters, 2005
Deinococcus radiodurans shows remarkable resistance to reactive oxygen species (ROS), generated by irradiation. Disruption of recX (dr1310) in D. radiodurans using targeted mutagenesis method enhanced its ROS scavenging activity, and recX overexpression in this bacterium repressed its antioxidant activity significantly. Further analyses on catalase and

RecX protein: Molecular insights into negative regulation of RecA protein and implications in HR processes

, 2023
Homologous recombination (HR) is essential for genome stability and for maintaining genetic diversity. In eubacteria, RecA protein plays a key role during DNA repair, transcription, and HR.

Mycobacterial recA is cotranscribed with a potential regulatory gene called recX [PDF]

Molecular Microbiology, 1997
The recA gene of Mycobacterium smegmatis has been cloned and sequenced. The amino acid sequence of the RecA protein is highly homologous to other RecA proteins. Three other potential open reading frames were identified. One of these showed extensive homology to a protein, HypB, involved in the incorporation of nickel into hydrogenases.

RecA Regulation by RecU and DprA During Bacillus subtilis Natural Plasmid Transformation

Frontiers in Microbiology, 2018
Natural plasmid transformation plays an important role in the dissemination of antibiotic resistance genes in bacteria. During this process, Bacillus subtilis RecA physically interacts with RecU, RecX, and DprA.
