Microbium. Thus, both genes were present in very early actinobacteria, but each gene has been lost many times in the later evolution of the phylum. These losses may conceivably have contributed to the evolution of branches such as Micrococcineae (Node 4 of Fig. 2) and Corynebacterineae (a sub-branch from node 6). The BldD regulon has been subjected to detailed analysis by immunoprecipitation of in
Al best hit to rsbN is found next to nearly all bldN orthologues in actinomycete genomes; but, strikingly, the RsbN-like proteins are much more divergent than their BldN target or most other families of orthologous proteins of actinobacteria (Fig 6). We speculate that this may imply differences in the signal responsiveness of different RsbN proteins, thereby contributing to the differences between

Itive search for orthologues of the 147 S. coelicolor TTA-containing genes (or in some cases gene clusters). We identified 19 that were widespread and frequently TTA-containing in 13 other Streptomyces genomes (Table 2). In addition, a further 10 genes or gene clusters frequently had TTA codons, even though their S. coelicolor orthologues were TTA-free (asterisks in Table 2). As 27/29 of the TTA-c

Translation (Nguyen et al., 2003; Takano et al., 2003). Translational regulation is via a very rare UUA codon in the adpA mRNA, falling between the segments encoding the two domains of AdpA. UUA is the only one of the six leucine codons to comprise only A and U residues, so the corresponding TTA codon is comparatively rare in GC-rich genomes ?it occurs in only 147 chromosomal genes in S. coelicolo
