Genentech has been working in collaboration with the ALS for years with the goal of identifying a better cholesterol treatment mechanism that targets a cholesterol-regulating protein in the body known as PCSK9. Recent advances in understanding PCSK9’s structure have put them closer to that goal. ... Read more »
A recently awarded National Institutes of Health (NIH) grant will help integrate existing structural biology resources at the ALS to better serve users. The funds will help establish a centralized collaborative mechanism, called ALS-ENABLE, that will guide users through the most appropriate routes for answering their biological questions. ...

Bacterial microcompartments (BMCs) are hollow protein shells that encapsulate enzymes involved in bacterial metabolism. Crystallography studies have provided atomic-resolution views of a fully assembled BMC, revealing basic principles of shell construction for fighting pathogens or bioengineering applications.

The Zika virus (ZIKV) is a mosquito-borne pathogen recently linked to birth defects in infants. At the ALS, researchers have resolved the structure of a key ZIKV protein to 3.0 Å, an important step toward the rational design of drugs capable of disrupting viral functions and halting the spread of the disease.

Scientists are providing the clearest view yet of an intact bacterial microcompartment (BMC), revealing the polyhedral structure and assembly of this organelle’s protein shell. Having the full structure can help provide important information in fighting pathogens or bioengineering bacterial organelles for beneficial purposes. ... Read more »
Scientists found that the element berkelium breaks form with its heavy-element peers by taking on an extra positive charge when bound to a synthetic organic molecule. This property could help scientists develop better methods for handling and purifying nuclear materials. ... Read more »
Proteins consisting of identical subunits arranged symmetrically around a central axis (cyclic homo-oligomers) play key roles in many biological processes. Researchers have now developed a systematic approach to their design and demonstrated its accuracy using protein crystallography and small-angle x-ray scattering. ... Read more »
Zika virus is a mosquito-borne infectious disease linked to certain birth defects in infants. Scientists have mapped a key viral protein called NS5, which contains two enzymes: one reduces the body’s ability to mount an immune response against infection and the other helps start the genetic replication process. ...

Using several spectroscopic techniques, scientists found that the element berkelium breaks form with its heavy-element peers by taking on an extra positive charge when bound to a synthetic organic molecule. This property could help scientists develop better methods for handling and purifying nuclear materials. ... Read more »
Malfunctions in the complex protein “machinery” of serotonin transport can result in depression, obsessive-compulsive disorder, aggression, anxiety, and Parkinson’s disease. Now, researchers have obtained x-ray crystallographic structures of the difficult-to-crystallize human serotonin transporter bound to two commonly prescribed antidepressant drug molecules.
