General annotation (Comments)

Function

Catalyzes the reversible oxidoreduction of molecular hydrogen, in conjunction with a specific electron acceptor, cytochrome c3.

Catalytic activity

2 H2 + ferricytochrome c3 = 4 H+ + ferrocytochrome c3.

Cofactor

Nickel.

Iron.

Subunit structure

Heterodimer of a large and a small subunit.

Subcellular location

Periplasm.

Miscellaneous

Perhaps the leader of the small subunit serves as a transport vehicle for both subunits.

Sequence similarities

Belongs to the [NiFe]/[NiFeSe] hydrogenase large subunit family.
