Group | [FeFe]-hydrogenases |
Subgroup | [FeFe] Group A3: Bifurcating |
Function | Bifurcates electrons from H2 to NAD and ferredoxin. Reverse reaction can also occur resulting in reoxidation of redox carriers concomitant with fermentative H2 evolution. |
Activity | Electron-bifurcation |
Oxygen tolerance | O2-labile |
Localisation | Cytosolic |
Ecosystem distribution | Gastrointestinal tracts, anoxic soils and sediments |
Taxonomic distribution | Widespread in anaerobic bacteria, including Firmicutes, Bacteroidetes, Deltaproteobacteria, and Spirochaetes |
Organisation 1: Thermotoga maritima (WP_004081677.1):
