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, ...

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 ...

Quality control is vital for the energy production of cells

Mitochondria generate most of the energy cells need through a respiratory chain for which they must produce their own proteins. The research group of Associate Professor Henna Tyynismaa, University of Helsinki, Finland, has ...

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. ...

Protein-like structures from the primordial soup

Experiments performed by ETH scientists have shown that it is remarkably easy for protein-like, two-dimensional structures—amyloids—to form from basic building blocks. This discovery supports the researchers' hypothesis ...

Brushing up peptides boosts their potential as drugs

Peptides promise to be useful drugs, but they're hard to handle. Because peptides, like proteins, are chains of amino acids, our bodies will digest them and excrete the remnants. Even if delivered to their targets intact ...

Physiologists uncover a new code at the heart of biology

UT Southwestern physiologists trying to understand the genetic code have found a previously unknown code that helps explain which protein should be created to form a particular type of cell.
