EC number
1.12.1.3
Accepted name
hydrogen dehydrogenase (NADP+)
Reaction
H2 + NADP+ = H+ + NADPH

hydrogen:NADP+ oxidoreductase
CAS registry number
9027-05-8
Comment
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 1.12.98.4, sulfhydrogenase). Different from EC 1.12.1.5, hydrogen dehydrogenase [NAD(P)+].
