FIG. 4.

(A) Schematic representation of the bacterial chromosomal attachment site (attB) of L. lactis subsp. cremoris 3107 containing part of a putative gene. The deduced gene product has homology to DNA ligases. Inverted repeats are drawn as thin arrows, and the common core is indicated as a boxed region. The nucleotide positions of the sequenced part of the ORF and of the common core are indicated as numbers. (B) Aligned nucleotide sequences of the regions containing attP, attL, attR, and attB. Phage TPW22 sequences are underlined, while the L. lactis subsp. cremoris 3107 chromosomal sequences are double underlined.
