β turns are the most common form of turns—a type of non-regular secondary structure in proteins that cause a change in direction of the polypeptide chain. They are very common motifs in proteins and polypeptides. Each consists of four amino acid residues. They can be defined in two ways: 1. By the possession of an intra-main-chain hydrogen bond between the CO of residue i and the NH of residue i+3; Alternatively, 2. By having a distance of less than 7Å between the Cα atoms of residues i and i+3. The hydrogen bond criterion is the one most appropriate for everyday use, partly because it gives rise to four distinct categories; the distance criterion gives rise to the same four categories but yields additional turn types.
Per is a Latin preposition which means "through" or "for each", as in per capita.
Tar is a viscous organic black liquid.
The Asx turn is a structural feature in proteins and polypeptides. It consists of three amino acid residues in which residue i is an aspartate (Asp) or asparagine (Asn) that forms a hydrogen bond from its sidechain CO group to the mainchain NH group of residue i+2. About 14% of Asx residues present in proteins belong to Asx turns.
The ST turn is a structural feature in proteins and polypeptides. Each consists of three amino acid residues in which residue i is a serine (S) or threonine (T) that forms a hydrogen bond from its sidechain oxygen group to the mainchain NH group of residue i + 2.
The Asx motif is a commonly occurring feature in proteins and polypeptides. It consists of four or five amino acid residues with either aspartate or asparagine as the first residue. It is defined by two internal hydrogen bonds. One is between the side chain oxygen of residue i and the main chain NH of residue i+2 or i+3; the other is between the main chain oxygen of residue i and the main chain NH of residue i+3 or i+4. Asx motifs occur commonly in proteins and polypeptides.
