CC   -!- FUNCTION: Part of a complex that provides reducing equivalents for
CC       heterodisulfide reductase. {ECO:0000250}.
CC   -!- SUBUNIT: The F420-non-reducing hydrogenase is composed of three
CC       subunits; MvhA, MvhD and MvhG. It forms a complex with the
CC       heterodisulfide reductase (hdr) (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the [NiFe]/[NiFeSe] hydrogenase small subunit
CC       family. {ECO:0000305}.
