Nucleotide sequence comparison of the attC recombination site of the aac(3)-Ic cassette from integron In182 with other attC recombination sites including that of the blaGES-1 cassette of integron In60 (4) (identical to that of the blaIBC-1 cassette [6]), those of the aac(3)-Ia cassettes from integron In4 (21) [identical to that of the aac(3)-Ia cassette from pUO901 (9)], integron InAB1 (7), and an integron of Acinetobacter baumannii AC-54/97 (8), and that of the aadA1 cassette of In2 (20). The termination codon of each resistance gene is underlined. The locations of the 1L, 2L, and 2R core sites of the recombination elements (19) are indicated by arrows. Residues that are conserved in other sequences, in comparison with the attC recombination site of the aac(3)-Ic cassette, are shaded.
