Almost all proteins have structural similarities to other proteins. Many of these structural similarities have evolutionary origins. Proteins are classified by family, super family, common folds, and class. Classification of Motifs Classification of Motifs are for proteins only.
Motifs are a combination of a few secondary structures.
They are sometimes referred to as super secondary structures. Most of the time are associated with a specific pattern of secondary structures. Motifs are formed by packing sidechains from adjacent secondary structures. When these secondary structures combine they form what is called domains. This is a brief example of how to find patterns within a sequence.
