Comments [?]

case <OC:Proteobacteria>
Function Catalyzes the prenylation of para-hydroxybenzoate (PHB) with an all-trans polyprenyl group. Mediates the second step in the final reaction sequence of ubiquinone-8 (UQ-8) biosynthesis, which is the condensation of the polyisoprenoid side chain with PHB, generating the first membrane-bound Q intermediate 3-octaprenyl-4-hydroxybenzoate.
Catalytic activity RHEA:27782: 4-hydroxybenzoate + all-trans-octaprenyl diphosphate = 4-hydroxy-3-all-trans-octaprenylbenzoate + diphosphate
EC 2.5.1.39
Pathway Cofactor biosynthesis; ubiquinone biosynthesis.
else case <OC:Cyanobacteria>
Function Catalyzes the prenylation of para-hydroxybenzoate (PHB) with an all-trans polyprenyl group. Mediates the second step in the final reaction sequence of plastoquinone-9 (PQ-9) biosynthesis, which is the condensation of the polyisoprenoid side chain with PHB, generating the first membrane-bound Q intermediate 4-hydroxy-3-solanesylbenzoate.
Catalytic activity RHEA:17709: 4-hydroxybenzoate + all-trans-nonaprenyl diphosphate = 4-hydroxy-3-all-trans-nonaprenylbenzoate + diphosphate
EC 2.5.1.39
end case
Cofactor Mg(2+)
Subcellular location Cell inner membrane; Multi-pass membrane protein.
Similarity Belongs to the UbiA prenyltransferase family.
