Superoxide Dismutase and Pseudocatalase Increase Tolerance to Hg(II) in <named-content content-type="genus-species">Thermus thermophilus</named-content> HB27 by Maintaining the Reduced Bacillithiol Pool

ABSTRACT Mercury (Hg) is a widely distributed, toxic heavy metal with no known cellular role. Mercury toxicity has been linked to the production of reactive oxygen species (ROS), but Hg does not directly perform redox chemistry with oxygen. How exposure to the ionic form, Hg(II), generates ROS is un...
