[NiFe] Group 1b-hydrogenase

This entry was last updated at: Feb. 9, 2018, 7:09 a.m.

Properties
Group [NiFe] Group 1: Respiratory H2-uptake [NiFe] hydrogenases
Subgroup [NiFe] Group 1b: Prototypical
Function Hydrogenotrophic respiration using sulfate, fumarate, nitrate, metals, and azo compounds as terminal electron acceptors. Enzyme transfers H2-liberated electrons through cytochromes to terminal reductase.
Activity H2-uptake (unidirectional)
Oxygen tolerance O2-sensitive
Localisation Membrane-bound or periplasmic
Distribution
Ecosystem distribution Anoxic soils and sediments, marine waters, animal gastrointestinal tracts
Taxonomic distribution Widespread in Deltaproteobacteria and Epsilonproteobacteria
Genetic Organisation

e.g. Wolinella succinogenes (WP_011139497.1):
