Proteins are the end products of the decoding process that starts with the information in cellular DNA. As workhorses of the cell, proteins compose structural and motor elements in the cell, and they ...

Proteins are made of amino acid chains, or polypeptides. Amino acids have a basic backbone made of an amino group and a carboxyl group, and differ in their side-chains. These polypeptide chains of ...

A new study by chemists shows that X-ray crystallography, the standard method for determining the structure of proteins, can provide inaccurate information about membrane proteins, which in turn could ...

Jane Richardson never considered herself an artist. Then, in the late 1970s, the structural biologist found herself in need of some colored pencils, pastels and sketching paper. Richardson, a ...

The structure of protein sets the foundation for its interaction with other molecules in the body and, therefore, determines its function. This article will cover the structural principles of proteins ...
