General annotation (Comments)

Function	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 geranylgeranyl diphosphate (GGPP; C20) as the prenyl donor. Ref.3
Catalytic activity	All-trans-heptaprenyl diphosphate + sn-glycerol 1-phosphate = diphosphate + sn-3-O-(all-trans-heptaprenyl)glycerol 1-phosphate. Ref.3
Cofactor	Magnesium By similarity. HAMAP MF_00112
Pathway	Membrane lipid metabolism; glycerophospholipid metabolism. HAMAP MF_00112
Subunit structure	Homodimer. Ref.3
Sequence similarities	Belongs to the GGGP/HepGP synthase family.
