A single protein bolted to the inner membrane of a bacterial cell can shred a virus’s DNA before that genetic material ever ...

Researchers have discovered a widespread mechanism in bacteria that enhances the bacteria's defense against environmental threats. The discovery, which may be important for research into developing ...

A research team has discovered a previously unknown mechanism by which the immune system fights bacterial infections. The ...

Bacterial cell wall synthesis and division represent central themes in microbiology, as these processes underpin cellular integrity, morphology and reproduction. The dynamic interplay between the ...

In what they labeled a "surprising" finding, Johns Hopkins Medicine researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the ...

Bacteria are the most diverse organisms on Earth, with a number of species that's difficult to quantify. They're also incredibly old Bacteria consist of a single cell. They do not have bones and are ...

A Franco-British team of scientists has explored two human proteins recently identified as immune enzymes. Structural studies in vitro show that, in a cell infected by a virus for example, these ...

The bacterial cell wall must be constantly remodeled in order to grow and divide. This involves the close coordination of lytic enzymes and peptidoglycan synthesis. Researchers led by Martin ...

Are all bacterial cells in a group alike? It doesn't seem so. A population of bacterial cells may be heteroresistant, which is to say that some may be able to evade the effects of antibiotics, while ...

Antibiotics are designed to kill harmful bacteria and help the body recover from infection. But some antibiotics may also ...
