Rice, UCSD scientists study genomes to reveal contacts, refine methods for protein-folding prediction José Onuchic has become an expert at connecting the dots, but finding connections merely implied by the dots “¦ well, that´s quite a trick. The Rice University biophysicist and his team have created a tool to do just that for proteins and, in the process, have advanced the art of predicting their form and function. In this case, the dots are amino acid...

In a pair of related studies, scientists from the Florida campus of The Scripps Research Institute have identified several proteins that help regulate cells´ response to light–and the development of night blindness, a rare disease that abolishes the ability to see in dim light. In the new studies, published recently in the journals Proceedings of the National Academy of Sciences (PNAS) and The Journal of Cell Biology, Scripps Florida scientists were able to show that a family of...

Researchers work to untangle knots, slipknots in species separated by a billion years of evolution Strings of all kinds, when jostled, wind up in knots. It turns out that happens even when the strings are long strands of molecules that make up proteins. A new study by scientists at Rice University and elsewhere examines structures of proteins that not only twist and turn themselves into knots, but also form slipknots that, if anybody could actually see them, might look like shoelaces...

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...

Insight may help the development of methods to treat diseases at the nanoscale Enabling bioengineers to design new molecular machines for nanotechnology applications is one of the possible outcomes of a study by University of Montreal researchers that was published in Nature Structural and Molecular Biology today. The scientists have developed a new approach to visualize how proteins assemble, which may also significantly aid our understanding of diseases such as Alzheimer's and...

(Ivanhoe Newswire) -- Contrary to earlier reports, a new study suggests that soy protein may not preserve overall thinking abilities in women over the age of 45, but may improve memory related to facial recognition. “Our study provides strong evidence that soy supplements should not be used by post menopausal women with the main goal of enhancing overall cognitive ability,” as quoted by Victor W. Henderson, MD, MS, with Stanford University. For the study, 313 healthy...

A new study suggests that protein knots, a structure whose formation remains a mystery, may have specific functional advantages that depend on the nature of the protein's architecture. "The presence of a knotted or slipknotted structure in a protein is relatively rare but really is very interesting," said Kenneth Millett, a professor of mathematics at UC Santa Barbara and a co-author of the paper, "Conservation of complex knotting and slipknotting patterns in proteins," published in the...

Connie K. Ho for redOrbit.com Tofu. Bean paste. These are just a few of the products that include soybean which is thought to have health benefits in the area of memory development. However, a new study has found that soy protein may not preserve overall thinking skills in middle-aged and older women who are over the age of 45; however, soy may be able to improve memory skills linked to facial recognition. The results are published in a recent edition of Neurology, the medical journal...
