Oxygen-tolerant H2 oxidation by membrane-bound [NiFe] hydrogenases of ralstonia species. Coping with low level H2 in air.

Abstract excerpt

Knallgas bacteria such as certain Ralstonia spp. are able to obtain metabolic energy by oxidizing trace levels of H2 using O2 as the terminal electron acceptor. The [NiFe] hydrogenases produced by these organisms are unusual in their ability to oxidize H2 in the presence of O2, which is a potent inactivator of most hydrogenases through attack at the active site. To probe the origin of this unusual O2 tolerance,...
