Figure 1

Genetic organization of the Srr-locus and emm—region in Streptococcus dysgalactiae. Panel A depicts a comparison of the novel srr-like locus detected in SDSD to the srr-operon of S. agalactiae. Two distinct srr variants have been described in S. agalactiae, denoted srr1 and srr2. The srr-like gene and rofA transcriptional regulator in SDSD is more similar to srr1 of S. agalactiae. However, the overall genetic organization of the SDSD srr-like operon resembles the srr2-locus, and is thus presented in the figure. The functional descriptions are inferred from the characterization of the srr-locus in S. agalactiae (ref Mistou (ref 10)). Panel B shows an alignment of the emm—region in SDSD and in human associated SDSE isolates. SDSD genomes harbour an additional gene, cspZ, predicted to encode a cell wall surface protein.
