[FeFe] Group A3-hydrogenase

This entry was last updated at: Feb. 9, 2018, 6:46 a.m.

Properties
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
Distribution
Ecosystem distribution Gastrointestinal tracts, anoxic soils and sediments
Taxonomic distribution Widespread in anaerobic bacteria, including Firmicutes, Bacteroidetes, Deltaproteobacteria, and Spirochaetes
