Progress and perspectives of surface layer proteins from Bacillus species—A review

Abstract:

Abstract:S-layer proteins are crystalline arrays composed of numerous identical protein or glycoprotein subunits． They comprise the outermost cell envelope component in most archaea and many bacteria． The remarkable properties of S-layer proteins are their capability to self-assemble and specific binding，which give S-layer proteins a wide application potential in nanotechnology and biomimetics． Recently most study in this field was concerned on the S-layer proteins of Bacillus species． This review provided a brief survey of the current state of the study about the genetics，function，properties，pathogenic correlation and application of the S-layer proteins of Bacillus species． The aim of this review was to gain more knowledge about the function of S-layers and lead to the development of new types of surface display system and recombinant vaccines，diagnostic agents and biocompatible surfaces．
