β-galactosidase activity assay of the putative −12/−24 promoters. Wild-type strain HD73 (•) and the sigL mutant (□). T0 is the end of exponential phase, and Tn is n hours after T0. (A) Promoter of HD73_5327 with lacZ fusion. (B) Promoter of HD73_0179 with lacZ fusion. (C) Promoter of HD73_2025 with lacZ fusion. (D) Promoter of HD73_4161 with lacZ fusion. (E) Promoter of HD73_1649 with lacZ fusion. (F) Promoter of HD73_4943 with lacZ fusion.
