摘要： Modified forms of naturally occurring bacteriocins, such as the R-type pyocins of Pseudomonas aeruginosa, are disclosed as are methods for producing them in GRAS organisms. The bacteriocins are modified at the ends of their tail fibers in a region responsible for binding specificity and affinity to their cognate binding partners, or receptors, such as those on the surface of bacteria. Methods for the use of the modified bacteriocins, such as to bind receptors, including virulence or fitness factors, on the surfaces of bacteria, are also described.
