Group | [NiFe] Group 1: Respiratory H2-uptake [NiFe] hydrogenases |
Subgroup | [NiFe] Group 1f: Oxygen-protecting |
Function | Unresolved role. Some enzymes mediate hydrogenotrophic respiration using O2 as a terminal electron acceptor. Enzyme also linked to protection from reactive oxygen species, protection of nitrogenase protection, and recycling of nitrogenase-derived H2. |
Activity | H2-uptake (unidirectional)? |
Oxygen tolerance | O2-tolerant? |
Localisation | Membrane-bound |
Ecosystem distribution | Various soil and aquatic environments |
Taxonomic distribution | Present in both aerobic soil bacteria (e.g. Actinobacteria) and anaerobic marine bacteria (e.g. Deltaproteobacteria) |
e.g. Geobacter sulfurreducens (WP_010940798.1):
