Escherichia coli 6-phosphogluconate dehydrogenase aids in tellurite resistance by reducing the toxicant in a NADPH-dependent manner

Exposure to the tellurium oxyanion tellurite (TeO3 2−) results in the establishment of an oxidative stress status in most microorganisms. […]

The ActP acetate transporter acts prior to the PitA phosphate carrier in tellurite uptake by Escherichia coli

The tellurium oxyanion tellurite is harmful for most microorganisms. Since its toxicity occurs chiefly once the toxicant reaches the intracellular […]
