The highly toxic oxyanion tellurite has to enter the cytoplasm of microbial cells in order to fully express its toxicity. Here we show that in the phototroph Rhodobacter capsulatus, tellurite exploits acetate permease (actP) to get into the cytoplasm and that the levels of resistance and uptake are linked.
Acetate permease (ActP) is responsible for tellurite (TeO32-) uptake and resistance in cells of the facultative phototroph Rhodobacter capsulatus

Abstract
The highly toxic oxyanion tellurite has to enter the cytoplasm of microbial cells in order to fully express its toxicity. Here we show that in the phototroph Rhodobacter capsulatus, tellurite exploits acetate permease (actP) to get into the cytoplasm and that the levels of resistance and uptake are linked.File in questo prodotto:
