Phage attachment sites. A) Schematic representation of the integration and excision of prophages. attP, attB, attL, and attR represent the phage attachment sites. Inward red arrows and outward green arrows indicate the PCR primers designed to amplify the attB and attP regions, respectively. B) Primer sequences for φLH-1 and φLH-2. C) Nucleotide sequences of the attachment sites for φLH-1 and φLH-2. Red letters represent the core sequences of the phage attachment sites. Blue and orange letters correspond to the left and right sequences of the prophage regions.
