Gram-negative bacteria deploy a range of protein toxins as mediators of inter-bacterial competition and pathogenicity. Among these, colicins comprise a class of ribosomally synthesised bacteriocins ...

Scientists from Cornell University, University of California, San Francisco (UCSF), and elsewhere have found that a surplus of membrane proteins may help bacteria survive antibiotic exposure. These ...

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 ...

Vancomycin is a common antibiotic used to treat gram-positive bacterial infections. It targets a key building block of the bacterial cell wall called Lipid II, but it can’t reach this lipid in ...
