Group | [FeFe]-hydrogenases |
Subgroup | [FeFe] Group C3: Phosphatase-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 serine/threonine phosphatase or AAA-type ATPase domains. Members of this class are co-transcribed with fermentative hydrogenases and appear to regulate their transcription. |
Activity | H2-sensing? |
Oxygen tolerance | O2-labile |
Localisation | Cytosolic |
Ecosystem distribution | Gastrointestinal tracts, anoxic soils and sediments |
Taxonomic distribution | Widespread in anaerobic bacteria, including Firmicutes, Deltaproteobacteria, and Spirochaete |
Organisation 1: Ruminococcus albus (WP_002849014.1):
Organisation 2: Geobacter sulfurreducens (WP_014552161.1):

Catalytic site | [FeFe]-centre |
FeS clusters | 2 [4Fe4S] clusters |
