description: YaaA is a key element of the stress response to H2O2. It acts by reducing the level of intracellular
  iron levels after peroxide stress, thereby attenuating the Fenton reaction and the DNA damage that this
  would cause [[cite:PUB00077122]]. The molecular mechanism of action is not known.
