[NiFe] Group 3c-hydrogenase

This entry was last updated at: June 13, 2016, 11:23 a.m.

Properties
Group [NiFe] Group 3: Cofactor-coupled bidirectional [NiFe] hydrogenases
Subgroup [NiFe] Group 3c: Heterodisulfide reductase-linked
Function Bifurcates electrons from H2 to heterodisulfide and ferredoxin. This is the final step in the Wolfe cycle of methanogenesis.
Activity Electron-bifurcation
Oxygen tolerance O2-tolerant?
Localisation Cytosolic
Distribution
Ecosystem distribution Methanogenic environments such as anoxic soils, marine sediments, and gastrointestinal tracts
Taxonomic distribution Encoded in most methanogens and sulfate-reducing bacteria
