FIG. 1.

(A) Schematic representation of the GBS rpoE region. The relative positions of the GBS rpoE homolog and flanking genes are represented by arrows. The positions of the Tn917 insertion, putative promoters (arrow), and transcriptional terminators (Ω) are also indicated. (B) Amino acid sequence alignment of delta proteins using CLUSTAL W (11) and BoxShade. Residues conserved in all five proteins are shown on a black background, and residues identical in three or more of the proteins are shown on a dark gray background. Similar residues are shown on a light gray background. Gaps introduced to maximize alignment are indicated by periods in the Bsu to Uu sequences. Species abbreviations: Bsu, B. subtilis; Bha, Bacillus halodurans; Mpn, M. pneumoniae; Mge, M. genitalium; Uu, Ureaplasma urealyticum.
