A team led by UCSD biochemists has discovered the mechanism by which a simple organism can produce 10 trillion varieties of a single protein, a finding that provides a new tool to develop novel drugs.
In the September 18 advance on-line publication of the journal Nature Structural and Molecular Biology, the researchers describe the mechanism by which a virus that infects bacteria—called a bacteriophage, or phage—can generate a kaleidoscope of variants of a particular protein. The paper will appear in print in Nature Structural and Molecular Biology in October.
Since this degree of protein diversity is extremely rare, recreating the process in a test tube could give researchers a new way to generate therapeutic enzymes, vaccines and other medically important proteins.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
