Accepted name: geranylfarnesylglycerol-phosphate geranylfarnesyltransferase
Reaction: all-trans-pentaprenyl diphosphate + sn-3-O-(farnesylgeranyl)glycerol 1-phosphate = 2,3-bis-O-(geranylfarnesyl)-sn-glycerol 1-phosphate + diphosphate
Other name(s): DGFGP synthase; 2,3-bis-O-(farnesylgeranyl)-sn-glycerol 1-phosphate synthase; 2,3-di-O-farnesylgeranylglyceryl synthase
Systematic name: all-trans-pentaprenyl diphosphate:sn-3-O-(pentaprenyl)glycerol 1-phosphate pentaprenyltransferase
Comments: 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, geranylgeranylglycerol-phosphate geranylgeranyltransferase.
