A powerful new method that combines high-resolution imaging and mass spectrometry is allowing the identification of proteins in a spatial context and providing a wealth of new insights into how ...

Scientists have for the first time looked deep into the protein structure that may determine our vision - and discovered that ...

The latter technique resulted in images so clear ... For years, the standard way to study protein structure was to form a crystal and study the way that crystal diffracts X-rays.

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...
