Science Detailed view of immune proteins could lead to new pathogen-defense strategies
Biologists at Berkeley Lab and UC Berkeley used cryo-EM to resolve the structure of a ring of proteins used by the immune system to summon support when under attack, providing new insight into potential strategies for protection from pathogens. The researchers captured the high-resolution image of a protein ring, called an inflammasome, as it was bound to flagellin, a protein from the whiplike tail used by bacteria to propel themselves forward.

Cell Host & Microbe Unlocking the secrets of Ebola
Scientists have identified a set of biomarkers that indicate which patients infected with the Ebola virus are most at risk of dying from the disease. The results come from one of the most in-depth studies ever of blood samples from patients with Ebola. Researchers found 11 biomarkers that distinguish fatal infections from non-fatal ones and two that, when screened for early upon symptom onset, accurately predict which patients are likely to die.

Nature Microbiology To find new biofuel enzymes, it can take a microbial village
In search of new plant enzymes? Try looking in compost. Researchers at JBEI have demonstrated the importance of microbial communities as a source of stable enzymes that could be used to convert plants to biofuels. This approach yields robust enzymes that researchers can't easily obtain from isolates.

ACS Catalysis Neutrons probe oxygen-generating enzyme for a greener approach to clean water
A new study sheds light on a unique enzyme that could provide an eco-friendly treatment for chlorite-contaminated water supplies and improve water quality worldwide. An international team of researchers used neutron analysis at Oak Ridge National Laboratory, X-ray crystallography and other techniques to study chlorite dismutase, an enzyme that breaks down the environmental pollutant chlorite into harmless byproducts. Their results advance understanding of the catalytic process involved to support future applications in bioremediation and biotechnology.
