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):
