Figure 4. S59-independent activation does not require the YtvA blue-light sensor.

Figure 4

Peak β-galactosidase accumulation from a ctc-lacZ fusion after 4% ethanol stress, in the presence or absence of YtvA (+YtvA or ΔYtvA). Strains encoded a minimal stressosome containing RsbRA as sole co-antagonist together with either wild type RsbS (PB1078 for +YtvA or PB1085 for ΔYtvA; open bars) or RsbS bearing the S59A substitution (PB1161 or PB1272; shaded bars). Error bars represent range in two independent assays.
