Protein structure is the three-dimensional arrangement of atoms in an amino acid-chain molecule. Proteins are polymers – specifically polypeptides – formed...

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

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

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

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

responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily...

ordered three-dimensional structure. This structure permits the protein to become biologically functional. The folding of many proteins begins even during the...

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

of protein structure prediction software summarizes notable used software tools in protein structure prediction, including homology modeling, protein threading...
