FIG. 5.

DNA alignment of 5′ untranslated regions ending at the start codon of six vpma genes and vspA from M. bovis (21). A putative Shine-Dalgarno (SD) sequence, the start point of transcription (+1), and the promoter element (−10) are indicated by lines above the sequence based on vspA. An inverted repeat is identified by half arrows. The box indicated with broken lines shows the minimum region where DNA cleavage must occur during recombination between vpma genes. The boxes indicated with solid lines show regions of complete identity between vspA and vpmaY sequences upstream from the minimum region of recombination. Asterisks represent identity between all sequences, and dashes indicate gaps introduced to optimize the alignment.
