FIG. 5.

Physical map of the alc locus of B. bronchiseptica. Blocks representing ORFs are drawn to scale from the 4.3-kb alcABC sequence determined by Giardina et al. (20) and from the sequence data for the 3.5-kb PstI DNA fragment presented in this study. PstI restriction sites (P), FBS upstream from alcA and alcR (black bars), and bcr′, the 5′ extremity of a putative bicyclomycin resistance gene downstream from alcR, are indicated.
