General annotation (Comments)
| Function | This enzyme recycles the H2 produced by nitrogenase to increase the production of ATP and to protect nitrogenase against inhibition or damage by O2 under carbon- or phosphate-limited conditions. |
| Catalytic activity | H2 + A = AH2. |
| Cofactor | Binds 1 nickel ion per subunit By similarity. |
| Subunit structure | Heterodimer of a large and a small subunit. |
| Subcellular location | |
| Sequence similarities | Belongs to the [NiFe]/[NiFeSe] hydrogenase large subunit family. |
