2. Fig. 1
Structures of 19 integrons subjected to sequence analysis. The 5' region of the class 1 integrons consists of the integrase gene intI1, the common promoter Pant, and the recombination site attI. Every gene cassette also carries a recombination sequence termed attC. The 3' region usually consists of the genes qacEΔ1 and sul1, as well as the open reading frame orfX.
