RsbU but not RsbT is required for opuCA–lacZ induction in response to energy stress. (a) Growth of wild-type strain PL13 following addition of the CCCP uncoupler at time 0. □, CCCP control (0 μM), containing 0.25 % ethanol; ▿, 5 μM CCCP; ▪, 10 μM CCCP; ▴, 25 μM CCCP. (b) Induction of opuCA–lacZ fusion activity in the wild-type cultures shown in (a). (c) CCCP (10 μM) was added to exponentially growing cells at time 0. ○, Wild-type strain (PL13); •, rsbT1 (PL14); ▵, sigB : : km (PL17); ▾, rsbUΔ1 (PL15).
