“…The observation that S-layers of cyanobacteria may induce precipitation of minerals (122,123) led to the concept of their use as templates for the formation of regular arrays of metal clusters as required in molecular electronics and nonlinear optics (27,105,124).…”

“…In addition, S-layers have also been employed as templates for the in situ nucleation of ordered two-dimensional arrays of CdS nanocrystals ( [44]. These results strongly support the fabrication of other inorganic nanocrystal superlattice arrays [42,71].…”

“…This interaction may also be used as the initial steps to form nanoclusters [42][43][44] [48,49]. In addition, it is now known that bacteria use horizontal genetic transfer of S-layer encoding genes to propagate their capacity to bind uranium [50].…”

“…Phosphate groups are also involved in the interaction of SLP from archaea Sulfolobus acidocaldarius DSM 639 with U(VI) [45]. With regard to the engineered SLPs, the introduction of thiol groups, mainly by adding cysteine residues [54] or by chemical modification of aminogroups with iminothiolane [42], was used to achieve a controlled deposition of gold nanoparticles, while the generation of chimeric His 6 -tagged-SLP improved nickel binding capacity of SLP from Ly. sphaericus [55,56] and effectiveness in removal of cadmium from water of SLP from Caulobacter crescentus [57].…”

“…For instance, the SLP of Ly. sphaericus was used to nucleate gold nanoclusters from thiol groups when exposed to a tetrachloroauric acid solution under electron radiation [42], or to nucleate Pd from carboxyl groups when exposed to a solution of Na 2 PdCl 4 [43]. The bound Pd(II) can be then reduced to the Pd(0) nanoclusters by the addition of H 2 , resulting in nanoparticles of 19-43 atoms with a diameter of approximately 1 nm very promising for the development of novel catalysts [37,58].…”

Surface-layers (S-layers) are macromolecular paracrystalline arrays of proteins or glycoproteins that can self-assemble into 2-dimensional semi-permeable meshworks to overlay the cell surface of many bacteria and archaea. They usually assemble into lattices with oblique, square or hexagonal symmetry and serve as an interface between the bacterial cell and the environment. Isolated S-layers can recrystallize into two-dimensional regular arrays in suspension or on various surfaces, thus being an appropriate material for several bionanotechnological purposes. Promising applications of S-layers include their use as biotemplates for the capture of metal ions or the synthesis of metal nanoclusters. Research ArticleInternational Journal of Biochemistry Research & Review, 3(1): 39-62, 2013 40 Considering the use of S-layers as biotemplates for the organization of metal ions or metallic nanoclusters, research on potential of surface layer proteins (SLP) and metals can be understood as an interdisciplinary field, in which different biophysical techniques supply complementary information. In this review, we discuss the SLP as native or engineered "bottom-up" building blocks for metal immobilization structures. We also describe the biophysical techniques used to analyze metal binding properties as well as the information obtained from the investigation of these structures.

Ein erstaunlich breites Anwendungspotential in der Biotechnologie, Biomimetik und Nanotechnologie ergaben Untersuchungen von Struktur, Chemie, Biosynthese, Genetik, Morphogenese und Funktion supramolekularer S‐Schicht‐Gitter („S”︁ für surface). Bei diesen handelt es sich um monomolekulare, kristalline Anordnungen aus Protein‐ oder Glycoprotein‐Untereinheiten; sie zählen zu den häufigsten Oberflächenstrukturen von prokaryotischen Zellen (siehe schematische Darstellung der Zellhülle eines Archaebakteriums).
