    • β-Turn conformers have been classified according to the rotational angles φ and ψ associated with the i+1 and i+2 residues, with βI, βII and βIII type turns being the most common. Less common are βI′ and βII′ type turns in which φ and ψ torsion angles of the central residues are opposite to those in the corresponding common turns C.M. Venkatachalam Biopolymers 6 1968 1425 1436
