[FeFe] Group B-hydrogenase Putative
This entry was last updated at: Feb. 9, 2018, 6:17 a.m.
Properties
| 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 |
Distribution
| Ecosystem distribution | Gastrointestinal tracts, anoxic soils and sediments |
| Taxonomic distribution | Widespread in colonic Bacteroides, Clostridia, and Actinobacteria |
Genetic Organisation
Organisation 1: Clostridium pasteurianum (WP_023976023.1):
Organisation 2: Clostridium carboxyidovorans (WP_007061531.1):
