Open any introductory biology textbook and one of the first things you’ll learn is that our DNA spells out the instructions for making proteins, tiny machines that do much of the work in our body’s cells. Results from a study published on Jan. 2 in Science defy textbook science, showing for the first time that the building blocks of a protein, called amino acids, can be assembled without blueprints – DNA and an intermediate template called messenger RNA (mRNA). A team of researchers has observed a case in which another protein specifies which amino acids are added. 

A research team led by physicists at the University of Wisconsin-Milwaukee (UWM) has proven a method that makes it possible to find the atomic structure of proteins in action by producing “snapshots” of them with unprecedented spatial and temporal resolution

The new method lets researchers identify weak and previously undetectable interactions between proteins inside living cells.

Integrating an INTEGRA VIAFLO 96 multichannel pipette into their high throughput expression facility has enabled Molecular Partners (Zurich, Switzerland) to streamline the discovery and development of a novel class of targeted protein therapeutics termed DARPins.

By tracking down how bacterial defense systems work, the scientists can potentially fight infectious diseases and genetic disorders.

Understanding just how sugar makes its way into the cell could lead to the design of better drugs for diabetes patients and an increase in the amount of fruits and vegetables farmers are able to grow.

Caltech researchers have developed a novel way to visualize proteins generated by microorganisms in their natural environment—including the murky waters of Caltech's lily pond, as in this image created by Professor of Geobiology Victoria Orphan and her colleagues. The method could give scientists insights to how uncultured microbes (organisms that may not easily be grown in the lab) react and adapt to environmental stimuli over space and time. 

Thermo Fisher Scientific has developed a high-resolution hydrophobic interaction chromatography (HIC) method that can separate a fusion protein from a truncated version and a structural isomer.

The previously unrecognized layer of biology could offer new drug targets.

Scientists identify protein in bacteria with essential role in survival
