The growing continuum in the variety of moonlighting functions paved the way for further elucidation of structural-functional aspects of protein evolution and design of proteins with novel functions. Currently, the moonlighting functions in various adhesive properties of surface layer proteins, an essential component of cell surface architecture of archaea and all phylogenetic groups of eubacteria become more prominently recognized. The remarkable credentials of surface layer proteins to self-assemble into supramolecular structures at nano-scale dimension have been exploited for the production of smart biomaterials in the form of biomimetics has been thrust area of research. The finely tuned topological features in terms of shape, size, geometry and surface chemistry of surface layer proteins are crucial for the production of biomimetics. The current developments of biomimetic lipid bilayers and composite membranes find applicability in understanding the functional dynamism of evolutionary relationship of bacterial cell envelopes and vaccine development, drug development and drug delivery. Though the development of biomimetics embraces fascination but faces with technological challenges. The plethora of literature has been available for the moonlighting aspects and nano-technological applications separately but none of the review describes towards the rhythmic transition from moonlighting functions of surface layer proteins of bacteria to biomimetics development and applications. Therefore, this review describes certain basic aspects of moonlighting functions and their mechanism of action, surface layer proteins and their moonlighting functions of commensal bacteria and their transition towards biomimetics. The recent developments of biomimetics based on surface layer proteins have been summarized and also posited different challenges and future prospects.展开更多
