CC   -!- FUNCTION: Catalyzes the prenylation of para-hydroxybenzoate (PHB) with
CC       an all-trans polyprenyl group. Mediates the second step in the final
CC       reaction sequence of ubiquinone-8 (UQ-8) biosynthesis, which is the
CC       condensation of the polyisoprenoid side chain with PHB, generating the
CC       first membrane-bound Q intermediate 3-octaprenyl-4-hydroxybenzoate.
CC       {ECO:0000255|HAMAP-Rule:MF_01635}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=4-hydroxybenzoate + all-trans-octaprenyl diphosphate = 4-
CC         hydroxy-3-all-trans-octaprenylbenzoate + diphosphate;
CC         Xref=Rhea:RHEA:27782, ChEBI:CHEBI:1617, ChEBI:CHEBI:17879,
CC         ChEBI:CHEBI:33019, ChEBI:CHEBI:57711; EC=2.5.1.39;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01635};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01635};
CC   -!- PATHWAY: Cofactor biosynthesis; ubiquinone biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_01635}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01635}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01635}.
CC   -!- SIMILARITY: Belongs to the UbiA prenyltransferase family.
CC       {ECO:0000255|HAMAP-Rule:MF_01635}.
