Advances of phage receptor binding proteins

Abstract:

Bacteriophages bind to the bacteria receptor through the receptor binding proteins (RBPs), a process that requires the involvement of complex atomic structures and conformational changes. In response to bacteriophage infection, bacteria have developed a variety of resistance mechanisms, while bacteriophages have also evolved multiple antagonistic mechanisms to escape host resistance. The exploration of the “adsorption-anti adsorption-escape process” between bacteriophages and bacteria helps us better understand the co-evolution process of bacteriophages and bacteria, which is important for the development of phage therapeutic technologies and phage-based biotechnologies. This review summarizes the bacteriophage adsorption related proteins, how bacteriophages escape host resistance based on the RBP alternations, and the recent progress of RBP-related biotechnologies.
