CC   -!- FUNCTION: Prenyltransferase that catalyzes in vivo the transfer of the
CC       heptaprenyl moiety of heptaprenyl pyrophosphate (HepPP; 35 carbon
CC       atoms) to the C3 hydroxyl of sn-glycerol-1-phosphate (G1P), producing
CC       heptaprenylglyceryl phosphate (HepGP). This reaction is an ether-bond-
CC       formation step in the biosynthesis of archaea-type G1P-based membrane
CC       lipids found in Bacillales. {ECO:0000255|HAMAP-Rule:MF_00112}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=all-trans-heptaprenyl diphosphate + sn-glycerol 1-phosphate =
CC         3-heptaprenyl-sn-glycero-1-phosphate + diphosphate;
CC         Xref=Rhea:RHEA:33495, ChEBI:CHEBI:33019, ChEBI:CHEBI:57685,
CC         ChEBI:CHEBI:58206, ChEBI:CHEBI:64781; EC=2.5.1.n9;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00112};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00112};
CC   -!- PATHWAY: Membrane lipid metabolism; glycerophospholipid metabolism.
CC       {ECO:0000255|HAMAP-Rule:MF_00112}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00112}.
CC   -!- SIMILARITY: Belongs to the GGGP/HepGP synthase family. Group I
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_00112}.
