Construction and confirmation of the ΔkojA_PkojA::wA and ΔkojA strains. (a) Change in the wA promoter region during construction of the ΔkojA_PkojA strain. (b) Construction of the ΔkojA_PkojA strain was confirmed by Southern hybridization. The site where the probe 1 hybridizes is shown. 1: ΔkojA, 2: ΔkojA_PkojA::wA. (c) Complementation of the niaD during construction of the ΔkojA strain. (d) Construction of the ΔkojA strain was confirmed by Southern hybridization. The site where the probe 2 hybridizes is shown. 3: ΔkojA_niaD-, 4: ΔkojA
