Common motif of arrangement of two antiparallel β-strands connected by a regular turn.

(atom colors)

use better example! Note: some side-chains have multiple conformations.

The prealbumin is a β-sandwich composed of an antiparallel and a mixed β-sheet. It forms a with the mixed β- sheets associated to a large transmolecular sheet.
Topology diagram of the monomer:

A consists of 4 antiparallel β-strands in the order bcda, i.e. the the 1st and 4th strand are adjacent and the 2nd and 3rd strand form a β-hairpin.
