Comparative analysis of sigma factor proteins and sigM gene regions of actinobacterial species. (A) Phylogenetic tree of actinobacterial sigma factors including the seven sigma factors of C. glutamicum ATCC 13032. The unrooted phylogenetic tree for different actinobacterial sigma factors is shown. Abbreviations: Cg, C. glutamicum; Ce, C. efficiens; Cd, C. diphtheriae; Cj; C. jeikeium; Ma, M. avium; Mt, M. tuberculosis; Sc, S. coelicolor. Scale bar, 0.1% amino acid substitution. (B) Comparison of the sigM gene regions of different actinobacteria. For corynebacteria, mycobacteria, nocardia, and streptomycetes, the organization of the sigM gene region is shown. The locations of the genes sigM, trxB, trxC, and cwlM are indicated. In mycobacteria, streptomycetes, and nocardia, a further gene of unknown function is located downstream of sigM.
