Group | [NiFe] Group 4: Respiratory H2-evolving [NiFe] hydrogenases |
Subgroup | [NiFe] Group 4c: Carbon monoxide-respiring |
Function | Forms respiratory supercomplex that couples CO oxidation at a carbon monoxide dehydrogenase to proton reduction at a CO-tolerant hydrogenase. The energy released is probably used to translocated protons through an unresolved mechanism. |
Activity | H2-evolution |
Oxygen tolerance | O2-tolerant |
Localisation | Membrane-bound |
Ecosystem distribution | In low abundance in anoxic soils |
Taxonomic distribution | Exclusive to carboxydotrophic Proteobacteria |
e.g. Carboxydothermus hydrogenoformans (WP_011344721.1):
