N each cluster co-evolved (results not shown). WhiJ paralogues in S. coelicolor vary considerably in their conservation in other organisms. One (SCO3421) was present in nearly all complex actinomycetes, and the adjacent gene encoding a likely antisigma factor nearly always contained a TTA codon in Streptomycineae (but in no other groups). Another present in all Streptomycineae (SCO4441) was also w
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

Twelve other S. coelicolor whiJ-like genes were represented in around half of streptomycetes (SCO2381*, 2865, 2869*, 3365*, 4176, 4301, 4678, 4998, 6129, 6537, 6629*, 7579) [asterisks indicate occurrence also in some other complex actinomycete(s)]; while seven others were found in four or fewer streptomycetes (SCO0704, 2246, 2253, 4543, 5125,Fig. 7.
