[FeFe] Group B-hydrogenase Putative

This entry was last updated at: Feb. 9, 2018, 6:17 a.m.

Properties
Group [FeFe]-hydrogenases
Subgroup [FeFe] Group B: Colonic-type
Function Unconfirmed role. Indirect evidence suggests the hydrogenase is involved in hydrogenogenic fermentation. It may couple reoxidation of ferredoxinred to the evolution of H2.
Activity H2-evolution?
Oxygen tolerance O2-labile
Localisation Cytosolic
Distribution
Ecosystem distribution Gastrointestinal tracts, anoxic soils and sediments
Taxonomic distribution Widespread in colonic Bacteroides, Clostridia, and Actinobacteria
