(2003): Crystallization of S-layer protein lattices on surfaces and interfaces
Prog. Organ. Coat., 47, 279-287 FullText FullText_BOKU

Abstract:
A review is given on the structure, chemistry, and assembly of crystalline bacterial cell surface layers (S-layers). S-layers composed of single protein or glycoprotein species represent the most common cell surface structures observed in prokaryotic organisms. Isolated S-layer proteins possess the intrinsic property for recrystallization into isoporous monomolecular arrays in suspension and at a broad spectrum of surfaces (e.g. silicon, metals, polymers) and interfaces (e.g. air-liquid interface or lipid films). The well-defined arrangement of functional groups on S-layer lattices allows the binding of functional molecules (e.g. enzymes, antibodies, ligands) and particles in defined regular arrays. S-layers also represent templates for the formation of inorganic nanocrystal superlattices (e.g. An, US, Pt) as required for molecular electronics and non-linear optics. Finally, S-layers can be used as the structural basis for a biomolecular construction kit involving all major species of biological molecules for applications in molecular nanotechnology, nanobiotechnology and biomimetics.
