Supplementary figure. DNA sequences of integration sites in 036, 036_X and 036_1d, and bacteriophages SfI and SfX. Sequences obtained by PCR and sequencing of junction regions using a series of primers across the integration site as described in the text. (A) attB in strain 036. (B) attP in phage SfI. (C) attP in phage SfX. (D) attL in strain 036_X. (E) attR in 036_X and 036_1d. (F) Sequence between phage SfI and SfX in strain 036_1d. Sequences in box are conserved DNA regions between genes; Underlined sequences are tRNA-thrW; Sequences in blue are att core sequence; Conserved genes flanking a given integration site are shaded and their transcription orientation is marked by an arrow.
