AbstractDuring evolution prokaryotes have developed different envelope structures exterior to the cell wall proper. Among these surface components are regularly arranged S-layers and capsules. The structural characterization and the detailed chemical analysis of these surface molecules is a...
AbstractS-layers are crystalline monomolecular assemblies of protein or glycoprotein, which represent one of the most common cell surface structures in Archaea and Bacteria. As porous lattices completely covering the cell surface they can provide prokaryotic cells with selection advantages by...
AbstractAlthough S-layers are being increasingly identified on Bacteria and Archaea, it is enigmatic that in most cases S-layer function continues to elude us. In a few instances, S-layers have been shown to be virulence factors on pathogens (e.g. Campylobacter fetus ssp. fetus and Aeromonas...
AbstractS-layers are now considered a common cell wall structure in Bacteria and Archaea as well as in some algae. Morphological and chemical studies have revealed that S-layers consist of crystalline arrays of protein or glycoprotein subunits forming oblique, square or hexagonal lattices on the...
AbstractThe wealth of information existing on the general principle of S-layers has revealed a broad application potential. The most relevant features exploited in applied S-layer research are: (i) pores passing through S-layers show identical size and morphology and are in the range of...
AbstractIn this chapter we report on the molecular biology of crystalline surface layers of different bacterial groups. The limited information indicates that there are many variations on a common theme. Sequence variety, antigenic diversity, gene expression, rearrangements, influence of...
