Definition

A motif of four consecutive residues that may contain one H-bond, which, if present, is between the main-chain CO of the first residue and the main-chain NH of the fourth. It is characterized by the dihedral angles of the second and third residues, which are the basis for sub-categorization. http://www.ebi.ac.uk/msd-srv/msdmotif/
