Group | [NiFe] Group 4: Respiratory H2-evolving [NiFe] hydrogenase |
Subgroup | [NiFe] Group 4d: Ferredoxin-coupled, Mrp-linked |
Function | Forms respiratory supercomplex that couples oxidation of ferredoxinred to reduction of protons to H2. The energy released is used to translocate Na+ ions through Mrp-like antiporter subunits to generate a sodium-motive force. |
Activity | H2-evolution |
Oxygen tolerance | O2-sensitive |
Localisation | Membrane-bound |
Ecosystem distribution | Hydrothermal vents, other high temperature ecosystems |
Taxonomic distribution | Exclusive to Thermococci and Aciduliprofundi |
e.g. Pyrococcus furiosus (WP_011012581.1):
