||A flavoprotein (FAD). The enzyme is involved in the biosynthesis of archaeal membrane lipids. It catalyses the reduction of all 8 double bonds in 2,3-bis-O-geranylgeranyl-sn-glycero-phospholipids and all 4 double bonds in 3-O-geranylgeranyl-sn-glycerol phospholipids with comparable activity. Unlike EC 126.96.36.199, 2,3-bis-O-geranylgeranyl-sn-glycerol 1-phosphate reductase [NAD(P)H], this enzyme shows no activity with NADPH, and requires a dedicated ferredoxin .
