Fig 1

(A) Schematic representation of the 7.1 kb element and pSEA2 insertion locations in E. coli TJ249. Yellow pentagons are the 7.1 kb element. The sequence from pSEA2 is indicated by a horizontal line. (B) Upper panel: Genetic organization of SE-6283 and SE-6945. Lower panel: Nucleotide sequences of imperfect inverted repeat motifs C and C’. Dots indicate that bases in C are identical to those in C’. (C) Presence of R-H-R-Y motif in IntA and IntB. IntA and IntB sequences are aligned with sequences of known tyrosine recombinases based on secondary structure prediction using PROMAL 3D [34]. The aligned regions corresponding to box I and box II in [35] are shown.
