CC   -!- FUNCTION: Involved in the synthesis of phylloquinone (vitamin K1).
CC       Catalyzes the transfer of a prenyl chain to 2-carboxy-1,4-
CC       naphthoquinone.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=1,4-dioxo-2-naphthoate + H(+) + phytyl diphosphate = CO2 +
CC         demethylphylloquinone + diphosphate; Xref=Rhea:RHEA:47740,
