Fig. 2.
Phylogenetic trees based on (a) istA-like sequences and (b) istB-like sequences from M. yongonense DSM 45126T and 16 other bacteria. The trees were constructed using the neighbor-joining method. Bootstrap values were calculated from 1,000 replications, and values of <50 are not indicated in the trees. The bars indicate the numbers of substitutions per amino acid position
