Figure 1. Beta-galactosidase activity in M. smegmatis expressing lacZ under the control of the promoter regions of the M. tuberculosis H37Rv lipF, pks2, msl3 and fadD21 genes.

Figure 1

The lipF, pks2, msl3 and fadD21 promoter-lacZ fusions carried by the pJEM15 plasmid were introduced into M. smegmatis. The positive control is M. smegmatis transformed with pJEM31(PAN) containing lacZ under the control of a mobile genetic element normalized against M. smegmatis transformed with pJEM15 empty vector. The results shown are the mean of two independent experiments.
