FIG. 1.

Nucleotide sequence of the B. anthracis vrrB ORF. The entire nucleotide sequence for the largest vrrB allele (K) is presented along with flanking regions containing the leuS gene (5′) and an unidentified ORF (3′). The deduced amino acid sequence of the vrrB ORF is shown below the nucleotide sequence. Known nucleotide differences among B. anthracis strains are shown above the nucleotide sequence. Putative amino acid changes within the vrrB ORF are shown below the amino acid sequence. The opposed arrows beneath the nucleotide sequence indicate regions of possible stem-loop structures. The arrows above the nucleotide sequence indicate ORFs. Putative RBS as well as start and stop codons are indicated by boxes.
