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}.
