FIG. 6.

Comparison of the gL10 recombination endpoints in the laboratory recombinant Rc13 and industrial isolate 5469. Top alignment, c2, 923, and Rc13; bottom alignment, 5447 and 5469. The numbering in the alignments starts from the A residues of the ATG codons of gL10 of c2 and 5469, respectively. Thin-line box indicates a fragment of the “insert” in the “long” gL10 genes of phages c2 and 5469. Shaded background indicates identities in each of the alignments. Darker-shaded background indicates sequences of the recombinants Rc13 and 5469 that match the short-L10 parent phages 923 and 5447, respectively. Sequences 5′ to these blocks in Rc13 and 9469 match the long-L10 parent phage c2 and an unknown parent phage, respectively. Thick-line box indicates the rows of the two alignments where the recombination endpoints are located.
