From hemoglobin that carries oxygen, to enzymes and hormones that turn cells on and off, to antibodies that fight infection, proteins seem to do it all. There are many different types of proteins, ...

With antibiotic-resistant bacteria on the rise, scientists have been searching for ways to shut down the Type IV secretion system (T4SS), a protein complex on the outer envelope of bacterial cells ...

A new study by chemists at the University of Arkansas shows that X-ray crystallography, the standard method for determining the structure of proteins, can provide inaccurate information about a ...

Life on Earth would not exist as we know it, if not for the protein molecules that enable critical processes from photosynthesis and enzymatic degradation to sight and our immune system. And like most ...

Neurons talk to each other using chemical signals called neurotransmitters. Scientists at St. Jude Children's Research Hospital have drawn on structural biology expertise to determine structures of ...

In an effort to reveal the inner workings of a protein that serves as a cell's damage detection system, scientists at Johns ...

When a protein folds, its string of amino acids wiggles and jiggles through countless conformations before it forms a fully folded, functional protein. This rapid and complex process is hard to ...

In the wee hours of an October morning, David Baker, a protein biologist at the University of Washington (UW), received the most-awaited phone call in a scientist’s career. Halfway around the world, ...

A new study on rubisco, a photosynthetic enzyme thought to be the most abundant protein on the planet, shows that proteins can change their structural arrangement with surprising ease. The findings ...
