[NiFe] Group 4e-hydrogenase

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

Properties

Group	[NiFe] Group 4: Respiratory H₂-evolving [NiFe] hydrogenases
Subgroup	[NiFe] Group 4e: Ferredoxin-coupled, Ech-type
Function	Forms respiratory complex that couples oxidation of ferredoxin_red to reduction of protons to H₂ in acetoclastic methanogenesis. This process appears to be coupled to sodium or proton translocation through the transmembrane modules. The complex can also act in the reverse direction during hydrogenotrophic methanogenesis.
Activity	Bidirectional
Oxygen tolerance	O₂-sensitive
Localisation	Membrane-bound

Distribution

Ecosystem distribution	Anoxic soils and sediments, animal gastrointestinal tracts
Taxonomic distribution	Encoded in multiple methanogenic orders and anaerobic bacteria

Genetic Organisation

e.g. Methanosarcina barkeri (WP_011305188.1):
