Domains of the tail fiber region of CJIE1-like prophages and construction of campycins. (A) Domains of H-fiber C. jejuni prophage CJIE1-like in comparison to prophage Mu and R2-pyocin. The H-fiber of CJIE1-like prophages harbors an N-terminal DUF3751 domain similar to the P. aeruginosa PAO1 R2-pyocin tail fiber encoded by prf15 (Williams et al., 2008). The gene downstream of the H-fiber gene is predicted to encode a DUF4376 domain as found in the U gene that functions as a chaperone for the Mu phage tail fiber (Haggard-Ljungquist et al., 1992). (B) For construction of campycin, the DUF3751 domain encoded by P. aeruginosa PAO1 R2-pyocin was fused with the C-terminus of the CAMSA2147 H-fiber.
