RpoS-dependent promoters require ppGpp for induction in the stationary phase. This has been thought to be a simple consequence of final sigma(S) itself requiring ppGpp for its production. By using four model promoters requiring final sigma(S) for normal induction in the stationary phase, we demonstrate that final sigma(S)-dependent promoters require ppGpp even in the presence of high levels of final sigma(S) produced ectopically. Similar to final sigma(70)-dependent promoters under positive… CONTINUE READING
