Bacterial interaction with plants and animals, symbiotic or pathogenic, involves the transfer to host cells and tissues of a range of bacterial proteins whose biochemical activities are key to ...

Many pathogenic bacteria use special secretion systems to deliver toxic proteins into host cells. Researchers of Ludwig-Maximilians-Universitaet (LMU) in Munich have determined the structure of a ...

Researchers have discovered a molecular 'barcode' system used by disease-causing bacteria to distinguish between beneficial and toxic molecules. Researchers at McMaster University have discovered a ...

Type VI secretion systems (T6SS) are sophisticated nanomachines that bacteria employ to inject effector proteins directly into neighbouring cells. These systems are structurally reminiscent of ...

Now Niederweis and colleagues at the University of Alabama at Birmingham describe the mechanism of secretion and trafficking of that toxin, TNT, which is the major cytotoxicity factor for the pathogen ...

You suddenly feel sick -- pathogenic bacteria have managed to colonize and spread in your body! The weapons they use for their invasion are harmful toxins that target the host's defense mechanisms and ...

The type III secretion system (T3SS) is a sophisticated molecular apparatus that many Gram‐negative bacterial pathogens deploy to inject effector proteins directly into host cells. This machinery ...

The system that allows the sharing of genetic material between bacteria – and therefore the spread of antibiotic resistance – has been uncovered by a team of scientists at Birkbeck, University of ...
