The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain.

Our brain's remarkable ability to form and store memories has long fascinated scientists, yet most of the microscopic ...

I will also describe the contributions of the general public to these efforts through the distributed computing project Rosetta@Home and the online protein folding and design game Foldit. Finally, I ...

Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha helices and beta sheets), tertiary (overall 3D shape), and quaternary (assembly of ...

Why is knowing the atomic structure of molecules useful? Learn why, and how information like this about protein structure is shared through a publicly available database. Scientists use a variety ...

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 ...

Protein complexes are important for the majority of vital processes in the cell and human body, such as producing energy, copying DNA and regulating the immune system.

For years, the standard way to study protein structure was to form a crystal and study the way that crystal diffracts X-rays. However, some proteins are difficult or even impossible to crystalize.

After translation, the polypeptide is finally folded into the correct shape and becomes a protein. Peptide bonds form between the adjacent amino acids to finalise the structure.
