Protein
Uptake hydrogenase small subunit
Organism
Oligotropha carboxidovorans (strain ATCC 49405 / DSM 1227 / KCTC 32145 / OM5)
Function
This enzyme recycles the H(2) produced by nitrogenase to increase the production of ATP and to protect nitrogenase against inhibition or damage by O(2) under carbon- or phosphate-limited conditions.
Similarity
Belongs to the [NiFe]/[NiFeSe] hydrogenase small subunit family.
