The dual significance of bacterial protein secretion

Secretion of bacterial proteins is an essential biological process with biotechnological and biomedical impact on human health. European scientists studied a universal and widely conserved bacterial secretory pathway towards ...

Coral reefs in warming seas

Disease outbreaks are often associated with hot weather. Because many bacteria typically multiply more rapidly in warmer conditions, it's a commonly held notion that warm-weather outbreaks are a straightforward consequence ...

Triple threat: One bacterium, three plasmids

Researchers from Australia found something completely new while conducting a genetic study of the pathogenesis of an enteric disease in birds. They report what is believed to be the first bacterial strain to carry three closely ...

Proteins enable essential enzyme to maintain its grip on DNA

Scientists have identified a family of proteins that close a critical gap in an enzyme that is essential to all life, allowing the enzyme to maintain its grip on DNA and start the activation of genes.

One Can Act Without Group Support; Even in the Bacterial World

(PhysOrg.com) -- A single bacterium can act alone, performing the same kinds of actions that a group normally does. The behavior of that bacterium can be manipulated at the cellular level. That’s the intriguing finding ...

Structural biology scores with protein snapshot

In a landmark technical achievement, investigators in the Vanderbilt Center for Structural Biology have used nuclear magnetic resonance (NMR) methods to determine the structure of the largest membrane-spanning protein to ...

New protein identified in bacterial arsenal

(PhysOrg.com) -- Nearly a billion years ago, bacteria evolved an insidious means of infecting their hosts — a syringe-like mechanism able to inject cells with stealthy hijacker molecules. These molecules, called virulence ...
