CC   -!- FUNCTION: Prenyltransferase that catalyzes the transfer of the
CC       geranylgeranyl moiety of geranylgeranyl diphosphate (GGPP) to the C3
CC       hydroxyl of sn-glycerol-1-phosphate (G1P). This reaction is the first
CC       ether-bond-formation step in the biosynthesis of archaeal membrane
CC       lipids. {ECO:0000255|HAMAP-Rule:MF_00112}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2E,6E,10E)-geranylgeranyl diphosphate + sn-glycerol 1-
CC         phosphate = diphosphate + sn-3-O-(geranylgeranyl)glycerol 1-
CC         phosphate; Xref=Rhea:RHEA:23404, ChEBI:CHEBI:33019,
CC         ChEBI:CHEBI:57677, ChEBI:CHEBI:57685, ChEBI:CHEBI:58756; EC=2.5.1.41;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00112};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00112};
CC   -!- PATHWAY: Membrane lipid metabolism; glycerophospholipid metabolism.
CC       {ECO:0000255|HAMAP-Rule:MF_00112}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00112}.
CC   -!- SIMILARITY: Belongs to the GGGP/HepGP synthase family. Group I
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_00112}.
