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

Hat this (partly) reflects differences in the complement of WhiJ-like signal transduction cascades. The strikingly reduced number of paralogues in S. venezuelae (one of several streptomycetes that lack a cluster orthologous to whiJ itself) may underpin the ability of S. venezuelae to sporulate exceptionally readily and comprehensively even in submerged culture, which has led to its adoption as a m

High percentage identity is indicated by the intensity of red, and low identity by the intensity of green.

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
