CC   -!- FUNCTION: Prenyltransferase that catalyzes the transfer of the
CC       geranylgeranyl moiety of geranylgeranyl diphosphate (GGPP) to the C2
CC       hydroxyl of (S)-3-O-geranylgeranylglyceryl phosphate (GGGP). This
CC       reaction is the second ether-bond-formation step in the biosynthesis of
CC       archaeal membrane lipids. {ECO:0000255|HAMAP-Rule:MF_01286}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2E,6E,10E)-geranylgeranyl diphosphate + sn-3-O-
CC         (geranylgeranyl)glycerol 1-phosphate = 2,3-bis-O-(geranylgeranyl)-sn-
CC         glycerol 1-phosphate + diphosphate; Xref=Rhea:RHEA:18109,
CC         ChEBI:CHEBI:33019, ChEBI:CHEBI:57677, ChEBI:CHEBI:58756,
CC         ChEBI:CHEBI:58837; EC=2.5.1.42; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01286};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01286};
CC   -!- PATHWAY: Membrane lipid metabolism; glycerophospholipid metabolism.
CC       {ECO:0000255|HAMAP-Rule:MF_01286}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_01286};
CC       Multi-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_01286}.
CC   -!- SIMILARITY: Belongs to the UbiA prenyltransferase family. DGGGP
CC       synthase subfamily. {ECO:0000255|HAMAP-Rule:MF_01286}.
