Fig 3. PSPTO_1043-dependent promoter activity.

Fig 3

Candidate promoter-containing regions were fused to the lux reporter gene in a plasmid. Lux expression was monitored after 6hr in WT or ΔPSPTO_1043/1042 strains carrying either the plasmid overexpressing PSPTO_1043 (PnptII-1043) or an empty vector. (A) A slight decrease in expression was observed in strains lacking PSPTO_1043/1042 (green bars) compared to WT (red bars) when no PSPTO_1043 was overexpressed. (B) Overexpression of PSPTO_1043 in both WT (green bars) and ΔPSPTO_1043/1042 (blue bars) results in increased expression from all the tested promoter fusions compared to strains lacking the overexpression construct (red bars).
