The study of an oxygen-sensing bacterial regulatory protein by chemistry researchers at the University of Georgia has provided molecular insight into the oxygen sensing mechanism, which could ultimately lead to a better understanding of the ageing process and new treatments for human diseases such cancer, Parkinson's and Alzheimer's. Michael Johnson, a distinguished research professor of chemistry in the UGA Franklin College of Arts and Sciences, and Bo Zhang, a UGA chemistry doctoral...

Splitting fluorescent protein helps image clusters in live cells Half a protein is better than none, and in this case, it's way better than a whole one. A Rice University lab has discovered that dividing a particular fluorescent protein and using it as a tag is handy for analyzing the workings of live cells, particularly in the way they employ iron-sulfur clusters. Iron and sulfur in just the right amounts are critical to good health. They're in the food people eat and vitamins they take...
