Group | [NiFe] Group 1: Respiratory H2-uptake [NiFe] hydrogenases |
Subgroup | [NiFe] Group 1h: Actinobacteria-type |
Function | Hydrogenotrophic respiration using O2 as terminal electron acceptor. Enzyme scavenges electrons from atmospheric H2 to fuel respiratory chain during carbon-starvation. Route of electron transfer unresolved. |
Activity | H2-uptake (unidirectional, high-affinity) |
Oxygen tolerance | O2-tolerant or O2-insensitive |
Localisation | Membrane-associated? |
Ecosystem distribution | Upland soils, plant tissues, possibly surface waters |
Taxonomic distribution | Widespread among obligately aerobic soil bacteria, especially Actinobacteria, Acidobacteria, and Chloroflexi |
e.g. Mycobacterium smegmatis (WP_003893634.1):
