Group | [FeFe]-hydrogenases |
Subgroup | [FeFe] Group B: Colonic-type |
Function | Unconfirmed role. Indirect evidence suggests the hydrogenase is involved in hydrogenogenic fermentation. It may couple reoxidation of ferredoxinred to the evolution of H2. |
Activity | H2-evolution? |
Oxygen tolerance | O2-labile |
Localisation | Cytosolic |
Ecosystem distribution | Gastrointestinal tracts, anoxic soils and sediments |
Taxonomic distribution | Widespread in colonic Bacteroides, Clostridia, and Actinobacteria |
Organisation 1: Clostridium pasteurianum (WP_023976023.1):
Organisation 2: Clostridium carboxyidovorans (WP_007061531.1):
