PAI, pathogenicity-associated island; NA, not applicable; SYN, synonymous; IS66, insertion sequence 66; +, genetic change present. Locus tags and chromosomal positions are given as in the reference JJ1886 genome.
For those genes without a designated name in the JJ1886 annotation, the homolog designation available from annotations of other E. coli strains was used. Genes encoding transcriptional regulators are shown in bold.
This chromosomal insertion of IS66 is not present in the originally published sequence of the JJ1886 genome.
