The enzyme, characterized from the archaeon Aeropyrum pernix, carries out the second prenyltransfer reaction involved in the formation of C25,C25 membrane diether-lipids in some archaea. Requires a divalent metal cation, such as Mg2+. The enzyme cannot accept sn-3-(O-geranylgeranyl)glycerol 1-phosphate as the prenyl donor. cf. EC 2.5.1.42, geranylgeranylglycerol-phosphate geranylgeranyltransferase.
