Scientists unveil piece of HIV protein that may be key to AIDS vaccine development

... to the inherently flexible nature of the chemical bonds in gp120. To overcome the problem, the investigators created a variety of gp120s and eventually made the protein stiff enough to capture a picture of it in complex with b12. They saw that b12 binds gp120 at the same point where gp120 initially attach...

Progress toward artificial photosynthesis?

...he biggest challenges in synthetic chemistry." The bonds in this molecule are very stable, so a lot of ener...alysts are known to be capable of breaking the C–O bonds in CO2. In contrast to most previous approaches, Antonietti’s team worked with metal-free catalys...

Cancer-killing invention also harvests stem cells

...ocess. First, he noted that the selectins form bonds with the white blood cells within fractions of a second, then immediately release the cells back into the bloodstream. He also realized that selectin is the adhesive mechanism by which bone marrow stem cells leave the bloodstream and find their way ...

Scientists see DNA get 'sunburned' for the first time

...NA." That damage consists of two tiny molecular bonds that form where they shouldn't -- between two thym...ey timed the reactions that caused the new thymine bonds to form. Kohler stressed that he and his colleagues examined damage to isolated DNA strands, not ...

York mathematician probes geometric route to combat viruses

...hat pinpoint the locations of the proteins and the bonds between them. With collaborators Professor Cristian Micheletti, from the International School for Advanced Studies (SISSA) in Trieste, Italy, and Professor Anne Taormina, from the University of Durham, she has used these results to model the assembly...

Progress toward an antitumor vaccine

...hotochemical) reaction, only the desired thioether bonds are formed—no side reactions occur at other locations in the peptide chain. “Synthetic glycopeptide antigens containing structural elements typical of tumors in the sugar as well as the protein segment,” explains Kunz, “can thus be attached to the...

Researchers examine carbon capture and storage to combat global warming

...arbon dioxide in deep coal beds. In coal, chemical bonds form between the carbon dioxide and the coal, making the method potentially more secure than others, the researchers said. Even better, the process can free natural gas that sits on the coal's surface. Natural gas is a relatively clean fossil fuel...

Simulations unravel outer membrane transport mechanism

...orce to TonB and showed that the multiple hydrogen bonds between TonB and the luminal domain were strong enough to remain intact while TonB pulled the end of the luminal domain away from the barrel. The simulation also showed the luminal domain gradually unfolding, changing its conformation in ways that wo...
