FIG. 2.

Structure of the IMU-made composite structure harboring the bla_GES-5 gene. (A) Schematic map of the putative mobilized structure on natural plasmid pCHE-A corresponding to the two IMUs bracketing the bla_GES-5-borne integron, with a truncated int1 integrase gene and a truncated qacE gene. The IRR and IRL identified in the IMU are indicated by black triangles. The 59-bp sequence of the bla_GES-5 gene cassette is indicated by a black oval, as is the oriV coding sequence region. The integron-mediated P_c and P₂ promoter sequences are indicated. (B) Schematic map of the fragment mobilized by the in trans transposition process onto recipient plasmid pOX38.
