FIG. 1.
Schematic of the region of GBS strain 2603 chromosome that contains the csrRS locus (wild type) and the corresponding chromosomal regions in mutant strains 2603csrRΔ and 515csrRΔ (csrRΔ mutants) and in mutant strains 2603csrSΔ and 515csrSΔ (csrS mutants). ORF designations are according to Tettelin et al. (36). Features of the predicted proteins are indicated in the table. Sp indicates the location of the spectinomycin cassette in csrRΔ; the broken line indicates the internal deletion in csrSΔ. aa, amino acids.
