Proteins are able to self-assemble into a wide range of highly ordered structures that feature a diverse array of properties. Through biomimicry — technological innovation inspired by nature — humans hope to emulate proteins and produce our own version of self-assembling molecules. A key to accomplishing this is understanding how protein-folding — a process critical to the form and function of a protein — is extended from individual proteins to complex assemblies....

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...

Hands-on Help For Learning The Secrets Of Molecules Provided By New Model

For biology researchers, the complex world of molecular proteins — where tens of thousands of atoms can comprise a single protein — may be getting clearer with the help of a new soft, transparent, and squishy silicone model they can hold in their hands. Its advantage over traditional computer and solid models is that it is mostly transparent and easy to manipulate, which will help researchers more intuitively understand protein structures, positions, and interactions. The models...

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...

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...

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...

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...

(Ivanhoe Newswire) -- The structure of biomolecules is of great interest for medicine and biology because their shape often determines their function. The use of new tools called free-electron lasers (FELs) allows scientists to obtain high-resolution structural insight into macromolecules. "The exceptionally intense X-ray pulses possible with FELs open the door for analyzing completely new classes of biomolecules like proteins from the cell membrane, that are hard or nearly impossible to...


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.'
