How protein complexes form in the cell

The formation of protein complexes is a highly organised process that does not begin with the "finished" proteins. Studies conducted by researchers at the Center for Molecular Biology of Heidelberg University (ZMBH) and the ...

Mutating Ebola's key protein may stop replication

Researchers may be able to stop the replication of Ebola virus by mutating its most important protein, according to a paper published in the Journal of Biological Chemistry.

Scientists create complex transmembrane proteins from scratch

It is now possible to create complex, custom-designed transmembrane proteins from scratch, scientists report this week. The advance, led by molecular engineers at the University of Washington Institute for Protein Design, ...

Plants feel the heat

It's not just humans and animals that suffer when the mercury rises, plants feel the heat too. Heat stress is a major issue in agriculture and can significantly reduce crop yield. Even small increases in temperature can affect ...

Sticking sugar to protein

ETH researchers have succeeded in determining the 3-D structure of the enzyme that attaches sugar chains to proteins – a breakthrough that they recently published in the journal Science.

How plants 'muscle up' against bacteria in the cold

Michigan State University scientists have furthered our understanding on how a plant protein, called CAMTA, helps plants strengthen themselves as they anticipate long periods of cold, such as three to four months of winter ...

Plant regulatory proteins 'tagged' with sugar

New work from Carnegie's Shouling Xu and Zhiyong Wang reveals that the process of synthesizing many important master proteins in plants involves extensive modification, or "tagging" by sugars after the protein is assembled. ...

Toxoplasma's balancing act explained

The parasite Toxoplasma gondii is a silent success. It infects up to 95% of people in many regions of the world, and most of them never know it, due to the parasite's artful manipulation of its host's immune response. Toxoplasma ...
