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=a 2,3-bis-O-phytanyl-sn-glycerol 1-phospholipid + 8 oxidized
CC 2[4Fe-4S]-[ferredoxin] = a 2,3-bis-O-(geranylgeranyl)-sn-glycerol 1-
CC phospholipid + 16 H(+) + 8 reduced 2[4Fe-4S]-[ferredoxin];

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}.
