Scientists determine tertiary structure of TehA membrane protein in Haemophilus bacteria

Proteins are molecular machines that transport substances, catalyze chemical reactions, pump ions, and identify signaling substances. They are chains of amino acids and the individual amino acid sequence is known for many of them. However, the functions a protein can carry out inside the cell are determined by the three-dimensional spatial structure of the protein. Establishing this so-called tertiary structure presents a great challenge to scientists.

BioSilta releases EnPresso tablet that regulates protein production in recombinant bacteria

BioSilta announces the release of the EnPresso Tablet Cultivation Set, a tabletised form of the patented EnBase technology. The EnBase technology is based on providing an enzymatic-controlled glucose supply in a fed-batch type manner, which allows an extended growth period and promotes higher final cell density.

Biologists determine three-dimensional structure of molecule involved in HIV, cancer

In a technical tour de force, structural biologists funded by the National Institutes of Health have determined the three-dimensional structure of a molecule involved in HIV infection and in many forms of cancer. The high-resolution structure sheds light on how the molecule functions and could point to ways to control its activity, potentially locking out HIV and stalling cancer's spread.

Researchers discover HIV-1 resists AZT drug

Rutgers researchers have discovered how HIV-1, the virus that causes AIDS, resists AZT, a drug widely used to treat AIDS. The scientists, who report their findings in Nature Structural & Molecular Biology, believe their discovery helps researchers understand how important anti-AIDS treatments can fail and could help AIDS researchers develop more effective treatment for the disease.

Discovery shows how cells decide what to recycle, unlocking debilitating disease's secret

Our bodies recycle proteins, the fundamental building blocks that enable cell growth and development. Proteins are made up of a chain of amino acids, and scientists have known since the 1980s that first one in the chain determines the lifetime of a protein. McGill researchers have finally discovered how the cell identifies this first amino acid - and caught it on camera.

Research on immune system can develop new therapy for inflammation, tumors

In two closely related studies, two teams of Scripps Research Institute scientists have discovered the underlying mechanisms that activate a type of immune cell in the skin and other organs. The findings may lead to the development of new therapies to treat inflammation, wounds, asthma, and malignant tumors.

Researchers clear hurdle on path toward gene-therapy treatment for disease

One of the most difficult aspects of working at the nanoscale is actually seeing the object being worked on. Biological structures like viruses, which are smaller than the wavelength of light, are invisible to standard optical microscopes and difficult to capture in their native form with other imaging techniques.

Australian scientists uncover the secrets behind one of nature’s most extraordinary biological machines

Scientists from the Victor Chang Cardiac Research Institute (VCCRI), Sydney, have discovered the secrets behind the tiny motors in bacteria that allow them to swim rapidly towards nutrients and away from toxins, which is crucial to the spread of bacterial infection. These motors can rotate at up to 100,000 revolutions per minute, yet can switch directions in milliseconds.
