For more than two decades, the International Space Station has provided a platform for growing and studying protein crystals. In the early days of microgravity research, scientists discovered that ...

Protein cages found in nature within microbes help weather its contents from the harsh intracellular environment -- an observation with many bioengineering applications. Researchers recently developed ...

Reporting in Science, researchers at UC Santa Barbara, UCSF and the University of Pittsburgh have developed a new workflow for designing enzymes from scratch, paving the way toward more efficient, ...

For those outside the chemistry cognoscenti, the announcement might have seemed little more than researchers patting each other on the back. But the question of protein folding had plagued scientists ...

How did life arise on Earth? Researchers have found among the first and perhaps only hard evidence that simple protein catalysts -- essential for cells, the building blocks of life, to function -- may ...

Biological targets represent a considerable test of our knowledge of the fundamental principles of molecular recognition. Effective modulation of biological events requires the generation of molecules ...

Human cells are full of proteins, which do everything from providing structure, to transporting molecules to new locations, to catalyzing the reactions that allow cells to divide and grow. Scientists ...

WHEN WE HUMANS got a first glimpse of our genome, we had good reason to question our biological complexity. Many scientists predicted we would possess some 100,000-plus genes, but sequencers finally ...

Proteins are life's molecular workhorses, doing everything from turning sunlight into food to fighting viruses. They are built from 20 different types of amino acid molecules, so even a small protein ...
