Natural and Engineered Hydroxyectoine Production Based on the Pseudomonas stutzeri ectABCD-ask Gene Cluster [PDF]

Applied and Environmental Microbiology, 2011
ABSTRACT We report on the presence of a functional hydroxyectoine biosynthesis gene cluster, ectABCD-ask , in Pseudomonas stutzeri DSM5190 T and evaluate the suitability of P.

Comparative Genomics and Phylogenomic Analysis of the Genus Salinivibrio [PDF]

, 2019
In the genomic era phylogenetic relationship among prokaryotes can be inferred from the core orthologous genes (OGs) or proteins in order to elucidate their evolutionary history and current taxonomy should benefits of that. The genus Salinivibrio belongs

Exploiting Substrate Promiscuity of Ectoine Hydroxylase for Regio- and Stereoselective Modification of Homoectoine

Frontiers in Microbiology, 2019
Extant enzymes are not only highly efficient biocatalysts for a single, or a group of chemically closely related substrates but often have retained, as a mark of their evolutionary history, a certain degree of substrate ambiguity.

The compatible solutes ectoine and 5-hydroxyectoine: Catabolism and regulatory mechanisms

, 2022
To cope with osmotic stress many microorganisms make use of short, osmotically active, organic compounds, the so-called compatible solutes. Examples for especially effective members of this type of molecules are the tetrahydropyrimidines ectoine and 5-hydroxyectoine.

Osmotic Imbalance, Cytoplasm Acidification and Oxidative Stress Induction Support the High Toxicity of Chloride in Acidophilic Bacteria

Frontiers in Microbiology, 2019
In acidophilic microorganisms, anions like chloride have higher toxicity than their neutrophilic counterparts. In addition to the osmotic imbalance, chloride can also induce acidification of the cytoplasm.

Implications for the Binding of the Protein G5P to DNA [PDF]

, 2015
Microorganisms accumulate molar concentrations of compatible solutes like ectoine to prevent proteins from denaturation. Direct structural or spectroscopic information on the mechanism and about the hydration shell around ectoine are scarce.

NMR spectra of PB2 627, the RNA-binding domain in influenza A virus RNA polymerase that contains the pathogenicity factor lysine 627, and improvement of the spectra by small osmolytes

Biochemistry and Biophysics Reports, 2017
The influenza A virus, which has an RNA genome, requires RNA-dependent RNA polymerase for transcription and replication. The polymerase is comprised of the subunits PA, PB1, and PB2. The C-terminal RNA-binding domain in PB2 contains lysine 627 (PB2 627),
