abstract：:Recent work has shown that Immunoglobulin-like (Ig-like) domains occur frequently on the surface of tailed dsDNA bacteriophages. Several of these Ig-like domains are added to bacteriophage structural proteins via programmed ribosomal frameshifts, and their evolutionary patterns suggest that they can be exchanged by ho...
