Figure 2.

The chromosomal regions of M. leprae and M. ulcerans similar to that of M. tuberculosis containing the glnA3 and glnA4 sequences show that these GS encoding sequences were disrupted by insertions (glnA3, M. ulcerans) or deletions (glnA3, M. leprae; glnA4, M. ulcerans). Similar genes are indicated in the same colour and the percentage amino acid identity to the M. tuberculosis H37Rv reference sequence is indicated between brackets. Open arrows indicate no significant similarity to sequences in the corresponding chromosomal regions.
