Group | [NiFe] Group 1: Respiratory H2-uptake [NiFe] hydrogenases |
Subgroup | [NiFe] Group 1b: Prototypical |
Function | Hydrogenotrophic respiration using sulfate, fumarate, nitrate, metals, and azo compounds as terminal electron acceptors. Enzyme transfers H2-liberated electrons through cytochromes to terminal reductase. |
Activity | H2-uptake (unidirectional) |
Oxygen tolerance | O2-sensitive |
Localisation | Membrane-bound or periplasmic |
Ecosystem distribution | Anoxic soils and sediments, marine waters, animal gastrointestinal tracts |
Taxonomic distribution | Widespread in Deltaproteobacteria and Epsilonproteobacteria |
e.g. Wolinella succinogenes (WP_011139497.1):
Structures |
|
Subunits | 3 |
Subunit description | HynB (hydrogenase large subunit) HynA (hydrogenase small subunit) HynC (cytochrome b subunit) In Deltaproteobacteria, CycA (cytochrome c3 subunit) substitutes for HynC |
Catalytic site | [NiFe]-centre |
FeS clusters | Proximal: 4Cys[4Fe4S] or 3Cys1Asn[4Fe4S] Medial: 3Cys[3Fe4S] Distal: 3Cys1His[4Fe4S] |
