beta turn,
β turns (also β-bends, tight turns, reverse turns, Venkatachalam 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.
One example of a connector involving secondary structure (i.e. hydrogen bonds between amide Hs and carbonyl Os of the backbone), is a reverse turn called the beta bend or beta turn. These turns often connect successive antiparallel beta strands and are then called beta hairpins.The Beta Turn Turns generally occur when the protein chain needs to change direction in order to connect two other elements of secondary structure. The most common is the beta turn, in which the change of direction is executed in the space of four residues.beta turn Beta Turn In this video, with stunning visual graphics, we present a detailed and informative discussion on protein secondary structural elements, mainly beta turns. We discuss the basic characteristic.Beta Turn At least eight forms of the beta turn occur, varying in whether a cis isomer of a peptide bond is involved and on the dihedral angles of the central two residues. The classical and inverse β-turns are distinguished with a prime, e.g., type I and type I′ beta turns.B-turns—types I, III—are nearly equivalent to a single turn of a 3 10-helix, stabilized by a 4→1 hydrogen bond and has been used with Aib as helix nucleating turn (Ravi, Prasad, & Balaram, 1983).
Beta turns, on the other hand, also known as reverse turns, are small loops that have less than four amino acid residues and cause abrupt changes in backbone direction. They are able to do this because they are stabilized by fixed internal hydrogen bonds unlike the loops.
