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.
Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha ... Understanding protein-protein interactions is crucial for deciphering cellular ...
"Many diseases are caused by mutations. Here we show that we can actually start with a gigantic, native protein complex and go all the way down to characterization of its primary structure and ...
