Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study. The study -- conducted using E. coli ...
The specific research of the Plummer-Medeiros lab focuses on how proteins in the membrane interact with lipids. This ...
Some eukaryotes consist of a single cell; but most single-celled creatures are made of simpler cells which lack obvious ...
Despite rapid advances in reading the genetic code of living organisms, scientists still face a major challenge today—knowing ...
MIT chemists have discovered the structure of a protein that can pump toxic molecules out of bacterial cells. Proteins similar to this one, which is found in E. coli, are believed to help bacteria ...
New research into antimicrobial peptides, small chains of amino acids able to damage bacterial cells, shows why some peptides are more effective at doing that and also why some cells are more ...
Viruses are so simple in their structure, they may not even qualify as living things. Yet, they are ruthless in their robotic ...
Abdominal pain is a hallmark of many digestive disorders, including inflammatory bowel disease and irritable bowel syndrome.
Researchers at the University of Toronto have discovered that bacteria can drive stem cell regeneration to repair the intestinal lining after injury—uncovering an unexpected way in which the gut ...
