Similar to passengers on an urban transit system, every protein made in the cell has a specific destination and function. Channels in cell membranes help direct these proteins to their appropriate target. Researchers at Boston University School of Medicine (BUSM) and their colleagues have now captured images of these channels as they open to allow proteins to pass through a membrane, while the proteins are being made. These findings are published as a Letter in Nature (Park, E. et al. 2013)....

Chemists at the California Institute of Technology (Caltech) have managed, for the first time, to simulate the biological function of a channel called the Sec translocon, which allows specific proteins to pass through membranes. The feat required bridging timescales from the realm of nanoseconds all the way up to full minutes, exceeding the scope of earlier simulation efforts by more than six orders of magnitude. The result is a detailed molecular understanding of how the translocon works....

Researchers from Hull, Bristol and Frankfurt have shown that a new technique for identifying molecular structure can be used effectively on small samples of biological proteins, particularly proteins that are targeted for drug development. The technique, an enhanced form of nuclear magnetic resonance (NMR) spectroscopy, could enable the structure of a protein to be identified within hours, rather than weeks or months, radically speeding up the process of drug discovery. The findings are...
