^a sequence of region flanking transposon insertion comes from the genome of Y. enterocolitica subsp. palearctica 105.5R(r) (NC_015224) deposited in the NCBI database.

^b lacZ is in the same orientation as the region with similarity to the database entry.

^c lacZ is in the opposite orientation to the region with similarity to the database entry.

^d + or-mean positive or negative OmpR-dependent regulation.
