[NiFe] Group 1h-hydrogenase
This entry was last updated at: Feb. 9, 2018, 3:51 a.m.
Properties
| Group | [NiFe] Group 1: Respiratory H2-uptake [NiFe] hydrogenases |
| Subgroup | [NiFe] Group 1h: Actinobacteria-type |
| Function | Hydrogenotrophic respiration using O2 as terminal electron acceptor. Enzyme scavenges electrons from atmospheric H2 to fuel respiratory chain during carbon-starvation. Route of electron transfer unresolved. |
| Activity | H2-uptake (unidirectional, high-affinity) |
| Oxygen tolerance | O2-tolerant or O2-insensitive |
| Localisation | Membrane-associated? |
Distribution
| Ecosystem distribution | Upland soils, plant tissues, possibly surface waters |
| Taxonomic distribution | Widespread among obligately aerobic soil bacteria, especially Actinobacteria, Acidobacteria, and Chloroflexi |
Genetic Organisation
e.g. Mycobacterium smegmatis (WP_003893634.1):

| Subunits | 3? |
| Subunit description | HyhL (hydrogenase large subunit) HyhS (hydrogenase small subunit) HyhE (putative iron-sulfur protein and proposed physiological electron acceptor) |
| Catalytic site | [NiFe]-centre |
| FeS clusters | Proximal: 3Cys1Asp[4Fe4S] Medial: 4Cys[4Fe4S] Distal: 3Cys1His[4Fe4S] |
Important Notes
The Robiginitalea biformata and Sulfolobus islandicus enzymes are relatively distantly related to the main group. No studies have yet tested whether these enzymes have a H2-scavenging role like other Group 1h [NiFe]-hydrogenases. They may instead represent founding members of a functionally-distinct lineage.
