New understanding of how bacteria build their protective cell wall

Using a series of chemical and genetic tricks to interrogate a dizzying cast of characters involved in the process of building a cell wall, researchers believe they have discovered the hidden identity of a key enzyme involved ...

Fighting bacteria—with viruses

Research published today in PLOS Pathogens reveals how viruses called bacteriophages destroy the bacterium Clostridium difficile (C. diff), which is becoming a serious problem in hospitals and healthcare institutes, due to ...

Scientists sleuth out proteins involved in Crohn's disease

(Phys.org) —University of Delaware researchers have identified a protein, hiding in plain sight, that acts like a bodyguard to help protect and stabilize another key protein, that when unstable, is involved in Crohn's disease. ...

Newly discovered mechanism could regulate gene activity

Many bacterial species have genes called mraZ and mraW, which are located in a cluster of genes that regulate cell division and cell wall synthesis. Despite the prevalence of these two genes, very little is known about their ...
