Latest Amino acid Stories
The novel Natural Sciences Repository aims to provide reliable information on various areas of scientific interest and presents its content in the simplest words and terms possible. The site has now added the categories Acid Residues and Acid Sequence to its Acid section. The first new category contains scientific information on amino acid residues, which are a by-product of the peptide formation process whereas the second newly included category contains scientific information on Acid...
Lee Rannals for redOrbit.com - Your Universe Online New clues have been unveiled that shed light on why living things use only molecules with specific orientations. Research analyzing meteorite fragments that fell on a frozen lake in Canada is providing strong evidence that liquid water inside an asteroid leads to a preference of left-handed over right-handed forms of common protein amino acids in meteorites. "Our analysis of the amino acids in meteorite fragments from Tagish Lake...
GREENBELT, Md., July 25, 2012 /PRNewswire-USNewswire/ -- Researchers analyzing meteorite fragments that fell on a frozen lake in Canada have developed an explanation for the origin of life's handedness - why living things only use molecules with specific orientations. The work also gave the strongest evidence to date that liquid water inside an asteroid leads to a strong preference of left-handed over right-handed forms of some common protein amino acids in meteorites. The result...
International collaboration puts molecular face on enzyme family that allows plants to adjust quickly to herbivore attack or changes in growing conditions Science has known about plant hormones since Charles Darwin experimented with plant shoots and showed that the shoots bend toward the light as long as their tips, which are secreting a growth hormone, aren’t cut off. But it is only recently that scientists have begun to put a molecular face on the biochemical systems that modulate...
Researchers at the University of Gothenburg, Sweden, are working to develop substances that can prevent parasites, bacteria and fungi from producing essential proteins, research that could, in the long term, lead to new drugs for several major diseases. The World Health Organization (WHO) has announced that aminoacyl-tRNA synthetases – a type of enzyme – are important targets for the development of new drugs for several major diseases such as cancer, various parasitic diseases and...
PASADENA, Calif., June 5, 2012 /PRNewswire/ -- Jacobs Engineering Group Inc. (NYSE:JEC) announced today it was awarded a contract from Evonik Methionine SEA Pte Ltd, a wholly-owned subsidiary of Evonik Industries AG, to provide engineering, procurement and construction management (EPCM) services for a new methionine production complex at Jurong Island, Singapore. Officials did not disclose the contract value, however noted that Jacobs is leading the project execution activities...
Salk scientists develop new technique for solving the structure of most popular targets for half of all drugs, potentially aiding discovery of new therapeutics A new method for rapidly solving the three-dimensional structures of a special group of proteins, known as integral membrane proteins, may speed drug discovery by providing scientists with precise targets for new therapies, according to a paper published May 20 in Nature Methods. The technique, developed by scientists at the Salk...
Extreme Human Physiologist Dr. Greg Wells of the University of Toronto Reacts To His First Experience With LivingFuel SuperEssentials Aminos On-Camera Orlando, FL (PRWEB) May 04, 2012 Dr. Greg Wells’ new book, "Superbodies: How The Science Behind World-Class Athletes Can Transform Your Body And Health," is scheduled for release in two weeks. Dr. Wells is an Associate Professor at the Faculty of Kinesiology & Physical Education at the University of Toronto and is also an Associate...
Protein design is technique that is increasingly valuable to a variety of fields, from biochemistry to therapeutics to materials engineering. University of Pennsylvania chemists have taken this kind of design a step further; using computational methods, they have created the first custom-designed protein crystal. Picking an ambitious design target with challenging features, the researchers’ success bodes well for the technique’s use in better understanding proteins’ makeup or using...
An international team of researchers has reported a new understanding of a little-known process that happens in virtually every cell of our bodies. Protein folding is the process by which not-yet folded chains of amino acids assume their specific shapes, hence taking on their specific functions. These functions vary widely: In the human body, proteins fold to become muscles, hormones, enzymes, and various other components. "This protein folding process is still a big mystery," said UC...
