A ΔmdtA::Kn mutant is more sensitive to sodium tungstate induction than the wild type. (a and b) β-Galactosidase assays were done with WT (TR530) and ΔmdtA::Kn (SL102) strains that were uninduced or induced by 5 mM sodium tungstate (a) or 10 μg/ml myricetin (b). (c) Complementation of ΔmdtA::Kn with pCA-mdtA (SL143) or the vector control (vc) pCA24N (SL142). Overexpression was induced with 0.1 mM IPTG either with or without 5 mM sodium tungstate. The error bars indicate standard deviations.
