Cellular stress defense

Small heat-shock proteins (sHSPs) are molecular chaperones that bind to unfolded proteins to prevent protein aggregation and defend against cellular stress. Mutations in human sHSPs are associated with inherited diseases ...

An RNA key that unlocks innate immunity

RNA has long been the neglected middle child of biomolecules, the go-between between DNA, which encodes the cell's instructions, and proteins, which carry them out. Increasingly, though, researchers are recognizing RNA as ...

Origin of life in membraneless protocells

How life arose from non-living chemicals more than 3.5 billion years ago on Earth is a still-unanswered question. The RNA world hypothesis assumes that RNA biomolecules were key players during this time as they carry genetic ...

The many structures of the light-active biomolecules

How the light-sensitive part of the biomolecule phytochrome changes from a light-adapted state to a dark-adapted state has been investigated by researchers at Ruhr-Universität Bochum and Philipps-Universität Marburg. So ...

Chemists discover unexpected enzyme structure

Many microbes have an enzyme that can convert carbon dioxide to carbon monoxide. This reaction is critical for building carbon compounds and generating energy, particularly for bacteria that live in oxygen-free environments.

Super-resolution microscopy builds multicolor 3-D from 2-D

Super-resolution microscopy is a technique that allows researchers to see beyond the diffraction limit of light. The technique has garnered increasing interest, especially since its developers won the Nobel Prize in Chemistry ...

Scientists created proteins controlled by light

Researchers have developed fluorescent proteins that can be controlled by orange and green light. These proteins will help to study processes in living cells. Results were published in Nature Methods.

Bacterial protein mimics DNA to sabotage cells' defenses

Infections with Salmonella bacteria, often caused by eating or handling undercooked meat or eggs, affect about 100 million people a year worldwide. The suffering the infection causes—abdominal cramps, fever and diarrhea—is ...

Hitchhikers hinder medication shelf life

Why some biopharmaceuticals have a longer shelf life than others is a problem that has baffled scientists and manufacturers alike. Even the same medication, produced by different manufacturers, can vary in its storage life.

New insights into the structure of a killer protein

Researchers at Ruhr-Universität Bochum and the University of Tübingen have gained new insights into the structure of the killer protein Bax. The protein induces programmed cell death, the method by which the body disposes ...
