By adding covalent bonds to proteins, researchers can design new drugs, imaging agents, or molecules that aid basic research Proteins are the workhorses of cells, adopting conformations that allow them to set off chemical reactions, send signals and transport materials. But when a scientist is designing a new drug, trying to visualize the processes inside cells, or probe how molecules interact with each other, they can't always find a protein that will do the job they want. Instead, they...

Big Molecule Models Captured In A Flash

Lawrence Berkeley National Laboratory To learn how biological molecules like proteins function, scientists must first understand their structures. Almost as important is understanding how the structures change, as molecules in the native state do their jobs. Existing methods for solving structure largely depend on crystallized molecules, and the shapes of more than 80,000 proteins in a static state have been solved this way. The majority of the two million proteins in the human body...

Berkeley Lab Researchers Unveil Technique for Easy Comparisons of Proteins in Solution A revolutionary X-ray analytical technique that enables researchers at a glance to identify structural similarities and differences between multiple proteins under a variety of conditions has been developed by researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab). As a demonstration, the researchers used this technique to gain valuable new...

Nanosponges Soak Up Toxins Released By Venom And Bacterial Infections

University of California - San Diego [ Watch The Video ] Engineers at the University of California, San Diego have invented a "nanosponge" capable of safely removing a broad class of dangerous toxins from the bloodstream — including toxins produced by MRSA, E. coli, poisonous snakes and bees. These nanosponges, which thus far have been studied in mice, can neutralize "pore-forming toxins," which destroy cells by poking holes in their cell membranes. Unlike other anti-toxin...

Nano-machines Developed Create 'Bionic Proteins'
2013-02-15 15:38:30

University of Vienna [ Watch The Video Animation Of Folding Pathway ] Physicists of the University of Vienna together with researchers from the University of Natural Resources and Life Sciences Vienna developed nano-machines which recreate principal activities of proteins. They present the first versatile and modular example of a fully artificial protein-mimetic model system, thanks to the Vienna Scientific Cluster (VSC), a high performance computing infrastructure. These "bionic...

By combining low temperatures and NMR spectroscopy, the scientists visualized seven intermediate forms of the CylR2 protein while cooling it down from 25°C to -16°C. Their results show that the most instable intermediate form plays a key role in protein folding. The scientists' findings may contribute to a better understanding of how proteins adopt their structure and misfold during illness. Whether Alzheimer's, Parkinson's or Huntington's Chorea — all three diseases have one...

Using an innovative approach, scientists at The Scripps Research Institute (TSRI) have determined the structure of Ltn1, a recently discovered “quality-control” protein that is found in the cells of all plants, fungi and animals. Ltn1 appears to be essential for keeping cells´ protein-making machinery working smoothly. It may also be relevant to human neurodegenerative diseases, for an Ltn1 mutation in mice leads to a motor-neuron disease resembling amyotrophic lateral...

By following a set of principles, scientists can produce protein molecules that previously did not exist in nature By following certain rules, scientists can prepare architectural plans for building ideal protein molecules not found in the real world. Based on these computer renditions, previously non-existent proteins can be produced from scratch in the lab. The principles to make this happen appear this month in Nature magazine. The lead authors are Dr. Nobuyasu Koga and Dr....

This month's cover story in Chemical & Engineering News (C&EN), the weekly news magazine of the American Chemical Society, is all about...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
