Dendograms of aligned actinobacterial GSIβ (encoded by glnA1) and GSII (encoded by glnA2) sequences constructed using PAUP 4.0 with the GS sequence of Bifidobacterium longum as out-group (*). Percentage bootstrap support values are shown. The ratio of nonsynonymous (Ka) to synonymous mutations (Ks) in the GS sequences of the mycobacteria and C. diphteria were computed using the GS sequences in C. efficiens, and is shown between brackets.
