title: Three-dimensional structure of the crystalline surface layer from Aeromonas hydrophila.
abstract: The three-dimensional (3D) structure of the crystalline surface layer of Aeromonas hydrophila has been determined to a resolution of 1.3 nm by crystallographic electron microscopy. The S-layer has tetragonal symmetry, with a unit cell dimension of 12.0 nm and a thickness of 5.6 nm. The 3D reconstruction reveals a distinct domain structure, with one main protein mass at one of the fourfold symmetry axes and a minor part at the other.
