CC   -!- FUNCTION: Catalyzes the formation of CDP-2,3-bis-(O-geranylgeranyl)-sn-
CC       glycerol (CDP-archaeol) from 2,3-bis-(O-geranylgeranyl)-sn-glycerol 1-
CC       phosphate (DGGGP) and CTP. This reaction is the third ether-bond-
CC       formation step in the biosynthesis of archaeal membrane lipids.
CC       {ECO:0000255|HAMAP-Rule:MF_01117}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2,3-bis-O-(geranylgeranyl)-sn-glycerol 1-phosphate + CTP +
CC         H(+) = CDP-2,3-bis-O-(geranylgeranyl)-sn-glycerol + diphosphate;
CC         Xref=Rhea:RHEA:25690, ChEBI:CHEBI:15378, ChEBI:CHEBI:33019,
CC         ChEBI:CHEBI:37563, ChEBI:CHEBI:58837, ChEBI:CHEBI:58838; EC=2.7.7.67;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01117};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01117};
CC   -!- PATHWAY: Membrane lipid metabolism; glycerophospholipid metabolism.
CC       {ECO:0000255|HAMAP-Rule:MF_01117}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_01117};
CC       Multi-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_01117}.
CC   -!- SIMILARITY: Belongs to the CDP-archaeol synthase family.
CC       {ECO:0000255|HAMAP-Rule:MF_01117}.
