FIG. 2.

Chromosomal location of the hdfR gene. The hdfR gene was previously divided into two ORFs, pssR and yifA, by E. coli genome sequencing for strain MG1655. Numbers indicate nucleotide positions, in kilobases. Arrows indicate directions of the ORFs. The nucleotide and deduced amino acid sequences of the hdfR gene have been submitted to GenBank (accession no. AF25103). ΔG indicates the location of the missing guanine nucleotide in the reported sequence (accession no. AE000453). The insertion site of TnphoA132 (Tn) is also indicated.
