hydrogenase (plural hydrogenases)
- (biochemistry) Any enzyme that catalyzes the reduction of a substrate by the reversible oxidation of hydrogen.
- 1930, Marjory Stephenson, LH Stickland, “Hydrogenase: a bacterial enzyme activating molecular hydrogen”, in Biochemical Journal:
- It is clear from the experiments cited already that we are dealing with a bacterial enzyme comparable with the dehydrogenases, the substrate in this case being molecular hydrogen. […] In order to conform with the accepted terminology we suggest that this enzyme be called "hydrogenase."
