The globally widespread genus Sulfurimonas: versatile energy metabolisms and adaptations to redox clines
TLDR
Sulfurimonas’ versatile energy metabolisms are summarized and their physiological properties to their global distribution are linked. Expand
Structure of Human RNase L Reveals the Basis for Regulated RNA Decay in the IFN Response
Crossed Homodimer Our cells respond to infection by releasing interferons, which protect neighboring cells, in part through the cleavage of intracellular RNA by a protein kinase family receptor,Expand
Innate immune messenger 2-5A tethers human RNase L into active high-order complexes.
TLDR
It is reported that human RNase L is activated by forming high-order complexes, reminiscent of the mode of activation of the phylogenetically related transmembrane kinase/RNase Ire1 in the unfolded protein response. Expand
A haem cofactor is required for redox and light signalling by the AppA protein of Rhodobacter sphaeroides
TLDR
A model for the transmission of light and redox signals by AppA is presented and it is shown that the haem binding domain is important for normal expression levels of photosynthesis genes and for normal light regulation in the presence of oxygen. Expand
The Role of Hydrogen for Sulfurimonas denitrificans’ Metabolism
TLDR
The first experimental evidence is shown that S. denitrificans can indeed express a functional hydrogen uptake active hydrogenase and can grow on hydrogen, and under the provided conditions it grew faster and denser on hydrogen than on thiosulfate alone and even grew with hydrogen in the absence of reduced sulfur compounds. Expand
A eukaryotic BLUF domain mediates light-dependent gene expression in the purple bacterium Rhodobacter sphaeroides 2.4.1.
TLDR
The results show that the hybrid protein is fully functional in light-dependent gene repression in R. sphaeroides, despite only approximately 30% identity between the eukaryotic and the bacterial BLUF domains. Expand
The AppA and PpsR Proteins from Rhodobacter sphaeroides Can Establish a Redox-Dependent Signal Chain but Fail To Transmit Blue-Light Signals in Other Bacteria
TLDR
The AppA/PpsR system could mediate redox-dependent gene expression in the alphaproteobacteria Rhodobacter capsulatus and Paracoccus denitrificans but not in the gammaproteinobacterium Escherichia coli, and was unable to establish light signaling in other bacteria. Expand
Sulfide Consumption in Sulfurimonas denitrificans and Heterologous Expression of Its Three Sulfide-Quinone Reductase Homologs
TLDR
This study provides the first experimental evidence of active epsilonproteobacterial SQRs and also gives the first report of a functional bacterial type III SQR. Expand
Hydrothermal chimneys host habitat-specific microbial communities: analogues for studying the possible impact of mining seafloor massive sulfide deposits
TLDR
Given that chimney structures can be considered SMS analogues, removal of sulfide deposits from the seafloor in the Kairei and Pelagia fields will most likely alter microbial compositions and affect element cycling in the benthic regions and probably beyond. Expand
