CC   -!- COFACTOR: Nickel (Potential).
CC   -!- SUBUNIT: The F420-non-reducing hydrogenase vhc is composed of
CC       three subunits; VhcA, VhcD and VhcG (By similarity).
CC   -!- INDUCTION: By selenium deprivation.
CC   -!- SIMILARITY: Belongs to the [NiFe]/[NiFeSe] hydrogenase large
CC       subunit family.
