hspX promoter activity in M. tuberculosis H37Rv and ΔRv2026c. The plasmid pMH108 carrying the hspX promoter region upstream of the firefly luciferase genes was transformed into Mtb H37Rv and ΔRv2026c. The promoter activity was measured in cultures grown under oxygen-sufficient conditions to mid-exponential phase and stationary phase and in cultures grown to hypoxic stationary phase. Relative light units (RLU) were determined and normalised using the OD of the cultures. The hspX promoter was seen to be active in both the wildtype and the ΔRv2026c mutants strain. Error bars represent the standard deviations of 3 independent cultures.
