Alphaviral Capsid Proteins Inhibit Stress Granule Assembly via Competitive RNA Binding With G3BP1

open access: yesAdvanced Science, EarlyView.
Stress granules exert antiviral functions. This study illustrates a conserved function of alphaviral capsid proteins in modulating stress granules. Oligomerization mediated by a helical motif coupled with a positively charged intrinsically disordered region (IDR) directly competes with G3BP1 for RNA binding, thereby disrupting G3BP1‐RNA liquid–liquid ...

Soil Viruses: A New Hope. [PDF]

open access: yes, 2019
As abundant members of microbial communities, viruses impact microbial mortality, carbon and nutrient cycling, and food web dynamics. Although most of our information about viral communities comes from marine systems, evidence is mounting to suggest that

Sensitive and specific detection of E. coli using biomimetic receptors in combination with a modified heat-transfer method [PDF]

open access: yes, 2019
We report on a novel biomimetic sensor that allows sensitive and specific detection of Escherichia colt (E. coli) bacteria in a broad concentration range from 10(2) up to 10(6) CFU/mL in both buffer fluids and relevant food samples (i.e.

Gut Microbe‐Driven Resistance Mechanisms in Propylea Japonica: Insights from Horizontal Gene Transfer and Oxidative Phosphorylation

open access: yesAdvanced Science, EarlyView.
Acinetobacter regulates dinotefuran tolerance in Propylea japonica by mediating the expression of the horizontally transferred gene PjDUF1. Abstract Insect–microbial symbiont relationships are widespread in nature and often involve lateral gene transfer.

Transient-mediated fate determination in a transcriptional circuit of HIV [PDF]

open access: yes, 2007
Steady-state behavior and bistability have been proposed as mechanisms for decision-making in gene circuits. However, transient gene expression has also been proposed to control cell fate with the decision arbitrated by the lifetime of the expression ...

What is Life? [PDF]

open access: yes, 2020
In searching for life in extraterrestrial space, it is essential to act based on an unequivocal definition of life. In the twentieth century, life was defined as cells that self-replicate, metabolize, and are open for mutations, without which genetic ...

Studies on Lysogeny in Staphylococci [PDF]

open access: yesJournal of General Microbiology, 1957
SUMMARY: A staphylococcus typing phage (NCTC 8426) was found to form lysogenic systems with three strains of staphylococci. In the case of two of these strains, staphylococci lysogenically infected with the typing phage were now lysed by the temperate phages they had previously carried. This loss of immunity was due to the replacement of the originally

Photon‐to‐Heat Energy Harvesting Fluorescent Protein Coatings for Thermoelectrics

open access: yesAdvanced Science, EarlyView.
Fluorescent proteins (FPs) are used in light‐absorbing coatings on thermoelectric generators (TEGs) to convert light into heat and generate electricity. By tuning the properties of FP‐doped polymer matrices, photothermal efficiencies of up to 48% have been achieved.

Bacteriophage 434 Hex Protein Prevents RecA-Mediated Repressor Autocleavage

open access: yesViruses, 2013
In a λimm434 lysogen, two proteins are expressed from the integrated prophage. Both are encoded by the same mRNA whose transcription initiates at the PRM promoter. One protein is the 434 repressor, needed for the establishment and maintenance of
