Streptomyces coelicolor and M. tuberculosis are both actinomycetes but have very different lifestyles. Their genomes reveal much similarity at the level of individual gene sequences, and many similar gene clusters. Global comparison showed perceptible higher-order synteny as well, shown as a dot plot in Fig. 2a. Determining transcriptional and translational regulatory elements in GC-rich Streptomyces genomes is essential to elucidating the complex regulatory networks that govern secondary metabolite biosynthetic gene cluster (BGC) expression.
