Group | [NiFe] Group 3: Cofactor-coupled bidirectional [NiFe] hydrogenases |
Subgroup | [NiFe] Group 3b: NADP-coupled |
Function | Directly couples oxidation of NADPH to fermentative evolution of H2. Reverse reaction may also occur. Some complexes controversially proposed to harbour sulfhydrogenase activity. |
Activity | Bidirectional |
Oxygen tolerance | O2-tolerant |
Localisation | Cytosolic |
Ecosystem distribution | Diverse soil and aquatic environments |
Taxonomic distribution | Encoded in multiple diverse bacterial and archaeal phyla |
e.g. Pyrococcus furiosus (WP_011012029.1):

Subunits | 4 |
Subunit description | HyhL (hydrogenase large subunit) HyhS (hydrogenase small subunit) HyhG (diaphorase catalytic subunit) HyhB (diaphorase electron transfer subunit) |
Catalytic site | [NiFe]-centre |
FeS clusters | Proximal: 4Cys[4Fe4S] Medial: 4Cys[4Fe4S] Distal: 4Cys[4Fe4S] |
