Group | [NiFe] Group 3: Cofactor-coupled bidirectional [NiFe] hydrogenases |
Subgroup | [NiFe] Group 3c: Heterodisulfide reductase-linked |
Function | Bifurcates electrons from H2 to heterodisulfide and ferredoxin. This is the final step in the Wolfe cycle of methanogenesis. |
Activity | Electron-bifurcation |
Oxygen tolerance | O2-tolerant? |
Localisation | Cytosolic |
Ecosystem distribution | Methanogenic environments such as anoxic soils, marine sediments, and gastrointestinal tracts |
Taxonomic distribution | Encoded in most methanogens and sulfate-reducing bacteria |
e.g. Methanothermobacter marburgensis (WP_013296307.1):
