Group | [FeFe]-hydrogenases |
Subgroup | [FeFe] Group C1: Histidine kinase-linked |
Function | Unconfirmed role. May serve as H2-sensors in regulatory cascades. Enzyme predicted to transfer H2-liberated electrons to PAS domain. Associated redox change may modulate activity of associated histidine kinase and in turn transcription if other hydrogenases. |
Activity | H2-sensing? |
Oxygen tolerance | O2-labile |
Localisation | Cytosolic |
Ecosystem distribution | Gastrointestinal tracts, anoxic soils and sediments |
Taxonomic distribution | Encoded in anaerobic bacteria, including Firmicutes and Bacteroidetes |
e.g. Acetobacterium woodii (WP_014357055.1):
Structures |
|
Subunits | 2 |
Subunit description | HydS (catalytic subunit with PAS domain) HydK (histidine kinase) |
Catalytic site | [FeFe]-centre |
FeS clusters | 2 [4Fe4S] clusters |
