Proteins are life’s molecular machines, built from amino acids whose sequences and side chains dictate their structure and function. From essential dietary amino acids to complex folding patterns, ...

A protein’s amino acid sequence helps determine its structure. Thus, proteins with similar sequences would be expected to have similar structures. But sometimes seemingly minor sequence changes can ...

For structural biologists, the molecular mapping of proteins is critical to figuring out their structure and function. But doing so takes patience and persistence. X-ray crystallography involves ...

Researchers at Ben-Gurion University of the Negev have identified simple rules that explain how complex protein structures ...

On Wednesday, the Nobel Committee announced that it had awarded the Nobel Prize in chemistry to researchers who pioneered major breakthroughs in computational chemistry. These include two researchers ...

In a finding that offers fresh insights into the early evolution of life on Earth, two RIKEN biologists have conducted lab experiments that have revealed a previously unknown protein fold, which is ...

When joined together and anchored to the inside of a cell membrane, this complex of three proteins (shown in salmon, purple, and green) plays a key role in cell replication, making it a potential ...

Scientists have for the first time looked deep into the protein structure that may determine our vision - and discovered that it is much more dynamic than previously thought. RBP3 not only changes its ...
