Protection of Methanosarcina barkeri against oxidative stress : identification and characterization of an iron superoxide dismutase

Methanosarcina barkeri is a methanogenic archaeon that can only grow under strictly anoxic conditions but which can survive oxidative stress. We have recently reported that the organism contains a monofunctional catalase. We describe here that it also possesses an active iron superoxide dismutase. T...
