CC -!- FUNCTION: Is involved in the reduction of 2,3-
CC digeranylgeranylglycerophospholipids (unsaturated archaeols) into 2,3-
CC diphytanylglycerophospholipids (saturated archaeols) in the
CC biosynthesis of archaeal membrane lipids. Catalyzes the formation of
CC archaetidic acid (2,3-di-O-phytanyl-sn-glyceryl phosphate) from 2,3-di-
CC O-geranylgeranylglyceryl phosphate (DGGGP) via the hydrogenation of
CC each double bond of the isoprenoid chains. {ECO:0000255|HAMAP-
CC Rule:MF_01287}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=8 A + a 2,3-bis-O-phytanyl-sn-glycerol 1-phospholipid = a 2,3-
CC bis-O-(geranylgeranyl)-sn-glycerol 1-phospholipid + 8 AH2;

CC Evidence={ECO:0000255|HAMAP-Rule:MF_01287};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2,3-bis-O-(phytanyl)-sn-glycerol 1-phosphate + 8 A = 2,3-bis-
CC O-(geranylgeranyl)-sn-glycerol 1-phosphate + 8 AH2;
CC Xref=Rhea:RHEA:64368, ChEBI:CHEBI:13193, ChEBI:CHEBI:17499,

CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01287};
CC Note=Binds 1 FAD per subunit. {ECO:0000255|HAMAP-Rule:MF_01287};
CC -!- PATHWAY: Membrane lipid metabolism; glycerophospholipid metabolism.
CC {ECO:0000255|HAMAP-Rule:MF_01287}.
CC -!- MISCELLANEOUS: Reduction reaction proceeds via syn addition of hydrogen
CC for double bonds. {ECO:0000255|HAMAP-Rule:MF_01287}.
CC -!- SIMILARITY: Belongs to the geranylgeranyl reductase family. DGGGPL
CC reductase subfamily. {ECO:0000255|HAMAP-Rule:MF_01287}.
