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:0000256|HAMAP- CC 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 ChEBI:CHEBI:58837, ChEBI:CHEBI:73125; Evidence={ECO:0000256|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 Xref=Rhea:RHEA:64376, ChEBI:CHEBI:13193, ChEBI:CHEBI:17499, CC ChEBI:CHEBI:138139, ChEBI:CHEBI:138140; Evidence={ECO:0000256|HAMAP- CC Rule:MF_01287}; CC -!- COFACTOR: CC Name=FAD; Xref=ChEBI:CHEBI:57692; CC Evidence={ECO:0000256|HAMAP-Rule:MF_01287}; CC Note=Binds 1 FAD per subunit. {ECO:0000256|HAMAP-Rule:MF_01287}; CC -!- PATHWAY: Membrane lipid metabolism; glycerophospholipid metabolism. CC {ECO:0000256|HAMAP-Rule:MF_01287}. CC -!- MISCELLANEOUS: Reduction reaction proceeds via syn addition of hydrogen CC for double bonds. {ECO:0000256|HAMAP-Rule:MF_01287}. CC -!- SIMILARITY: Belongs to the geranylgeranyl reductase family. DGGGPL CC reductase subfamily. {ECO:0000256|HAMAP-Rule:MF_01287}. CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ CC whole genome shotgun (WGS) entry which is preliminary data. CC {ECO:0000313|EMBL:HIP16434.1}.
