Proteomics News - October 2011 Archives
Researchers have built a map that shows how thousands of proteins in a fruit fly cell communicate with each other. This is the largest and most detailed protein interaction map of a multicellular organism, demonstrating how approximately one third of the proteins cooperate to keep life going.

In a report to be published soon in EPJE, researchers from the National University of the South in Bahia Blanca, Argentina, studied the condition for model cavity and tunnel structures resembling the binding sites of proteins to stay dry without losing their ability to react, a prerequisite for proteins to establish stable interactions with other proteins in water.

Scientists from the Faculty of Biology and Biotechnology at the RUB have published a report in the Journal of Biological Chemistry explaining why enzymes used for the production of hydrogen are so sensitive to oxygen. In collaboration with researchers from Berlin, they used spectroscopic methods to investigate the time course of the processes that lead to the inactivation of the enzyme's iron center.

 | A new book, "Protein Homeostasis", from Cold Spring Harbor Laboratory Press covers the entire spectrum of protein homeostasis in healthy cells and the diseases that result when control of protein production, protein folding, and protein degradation goes awry. ...> Full Article |
 | Molecular motion in proteins comes in three distinct classes, according to a collaboration by researchers at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, in research reported in Physical Review Letters. ...> Full Article |
 | Three international teams of scientists, led by researchers at the University of California San Diego, University of Michigan and Stanford University, have published a trio of papers describing in unprecedented detail the structure and workings of G protein-coupled receptors (GPCRs), a large family of human proteins that are the target of one-third to one-half of modern drugs. ...> Full Article |
