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}.
