UniProtKB description:  Prenyltransferase that catalyzes in vivo the transfer of the heptaprenyl moiety of heptaprenyl pyrophosphate (HepPP; 35 carbon atoms) to the C3 hydroxyl of sn-glycerol-1-phosphate (G1P), producing heptaprenylglyceryl phosphate (HepGP). This reaction is an ether-bond-formation step in the biosynthesis of archaea-type G1P-based membrane lipids found in Bacillales. To a much lesser extent, is also able to use geranyl diphosphate (GPP; C10) and geranylgeranyl diphosphate (GGPP; C20) as the prenyl donors, but not farnesyl pyrophosphate (FPP; C15). Cannot use glycerol-3-phosphate (G3P) or 3-phosphoglycerate (3PG) as an acceptor.
