The protein from the bacterium Desulfovibrio fructosovorans is an iron-sulfur protein that exclusively functions as a hydrogen dehydrogenase [1], while the enzyme from the archaeon Pyrococcus furiosus is a nickel, iron, iron-sulfur protein, that is part of a heterotetrameric complex where the alpha and delta subunits function as a hydrogenase while the beta and gamma subunits function as sulfur reductase (EC, sulfhydrogenase). Different from EC, hydrogen dehydrogenase [NAD(P)+].
