Activation ofbsaMandbsaNpromoters by BprP inE. coli. The ability of BprP to directly activate the expression of promoters in the presence and absence of BprQ was examined by providing the bprP and bprQ genes in trans and measuring β-galactosidase activities arising from the expression of transcriptional promoter-lacZ fusions in E. coli DH5α. A. Effect of BprP and BprQ on the expression of PbsaN-lacZ fusion. B. Effect of BprP and BprQ on the expression of PbsaM-lacZ fusion. C. Effect of BspR on the expression of PbprP-lacZ fusion. *p < 0.05.
