Protein structure prediction is the inference of the three-dimensional structure of a protein from its amino acid sequence—that is, the prediction of...

Protein quaternary structure is the fourth (and highest) classification level of protein structure. Protein quaternary structure refers to the structure...

Protein secondary structure is the local spatial conformation of the polypeptide backbone excluding the side chains. The two most common secondary structural...

Protein primary structure is the linear sequence of amino acids in a peptide or protein. By convention, the primary structure of a protein is reported...

Protein tertiary structure is the three-dimensional shape of a protein. The tertiary structure will have a single polypeptide chain "backbone" with one...

a protein structure database is a database that is modeled around the various experimentally determined protein structures. The aim of most protein structure...

Protein quinary structure refers to the features of protein surfaces that are shaped by evolutionary adaptation to the physiological context of living...
