[NiFe] Group 1d-hydrogenase

This entry was last updated at: Feb. 9, 2018, 7:26 a.m.

Properties
Group [NiFe] Group 1: Respiratory H2-uptake [NiFe] hydrogenases
Subgroup [NiFe] Group 1d: Oxygen-tolerant
Function Hydrogenotrophic respiration using O2 or fumarate as terminal electron acceptors. Enzyme transfers H2-liberated electrons through cyt b and quinone to terminal reductase.
Activity H2-uptake (unidirectional)
Oxygen tolerance O2-tolerant
Localisation Membrane-bound
Distribution
Ecosystem distribution Diverse soil, aquatic, and host-associated environments
Taxonomic distribution Widespread among obligately aerobic and facultatively anaerobic bacteria
Genetic Organisation
