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, ...

Overview of the PSP pipeline. Following genomic sequencing, the primary amino acid sequence is determined. The experimental method then starts with expressing this protein by genetically modifying ...

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 ...

Tuberculosis is one of the top ten causes of death worldwide, infecting about one-quarter of the world's population. Although it is treatable, the rise of multidrug-resistant tuberculosis poses a ...
