FIG. 1.

Nucleotide sequence and predicted amino acid sequence of the plasmid-mediated aadA-1 gene of E. faecalis W4770. The 1,009-bp PCR product was amplified with oligonucleotide primers specific for the integron cassette described by Lévesque et al. (21, 22). The gene insertion sites (GTTA) for the integron, at the 3′ end of each of the two shaded areas which highlight the hs2 (14 bp) and hs1 (55 bp) hot spots; the initiation and stop codons are in boldface type; and the 59-bp element is underlined (28).
