FIG 2 .

Presence of genes responsible for d-galactose transport (galP, mglBAC), utilization (galETKM), and regulation of these two processes (galR, galS, crp, spf) in genomes of strains belonging to the Enterobacteriaceae family (GenBank accession numbers are shown on the left, and more details are provided in Materials and Methods). Filled boxes indicate the presence of intact genes, based on bioinformatical analysis. Empty boxes indicate genes disrupted by extensive deletions or insertions. The galM pseudogene of Y. pestis, which is inactivated by a single-base-pair deletion, is marked by an asterisk. Arrowheads indicate the direction of transcription for putative operons and ORFs separated by less than 1 kbp.
