Accepted name: hydrogen dehydrogenase (NADP+)
Reaction: H2 + NADP+ = H+ + NADPH
Other name(s): NADP+-linked hydrogenase; NADP+-reducing hydrogenase; hydrogenase (ambiguous); hydrogenase I (ambiguous)
Systematic name: hydrogen:NADP+ oxidoreductase
Comments: 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 α and δ subunits function as a hydrogenase while the β and γ subunits function as sulfur reductase (EC, sulfhydrogenase). Different from EC, hydrogen dehydrogenase [NAD(P)+].
