A beta turn is a secondary structure element consisting of four consecutive amino acids (or three peptide planes). The geometry of turns correspond to a change in the direction of the polypeptide backbone, allowing them to connect alpha helices and beta strands at the surface of a globular protein. Of the six main chain hydrogen bonding partners of a turn, a maximum of two are engaged in hydrogen bonding, and turns are rarely found in the hydrophobic core.
