 "Structure and mechanism of the magnesium-independent aromatic
 prenyltransferase CloQ from the clorobiocin biosynthetic pathway.";
 J. Mol. Biol. 404:611-626(2010).
 -!- FUNCTION: Magnesium-independent aromatic prenyltransferase that
     catalyzes the irreversible transfer of a dimethylallyl group to 4-
     hydroxyphenylpyruvate to produce the ring A structure in the
     clorobiocin biosynthesis pathway. Clorobiocin is an aminocoumarin
     family antibiotic. {ECO:0000269|PubMed:12618544}.
 -!- CATALYTIC ACTIVITY: Dimethylallyl diphosphate + 4-
     hydroxyphenylpyruvate = diphosphate + 3-dimethylallyl-4-
     hydroxyphenylpyruvate. {ECO:0000269|PubMed:12618544}.
 -!- BIOPHYSICOCHEMICAL PROPERTIES:
     Kinetic parameters:
       KM=25 uM for 4-hydroxyphenylpyruvate
       {ECO:0000269|PubMed:12618544};
       KM=35 uM for dimethylallyl diphosphate
       {ECO:0000269|PubMed:12618544};
 -!- PATHWAY: Antibiotic biosynthesis. {ECO:0000269|PubMed:12618544}.
 -!- SUBUNIT: Monomer. {ECO:0000269|PubMed:12618544,
     ECO:0000269|PubMed:17077503, ECO:0000269|PubMed:20946900}.
 -!- DISRUPTION PHENOTYPE: Cells lacking this gene produce antibiotic
     compounds (vanillobiocin, isovanillobiocin and declovanillobiocin)
     with a methoxy instead of the dimethylallyl group at the position
     3 of the 4-hydroxybenzoic acid moiety of clorobiocin.
     {ECO:0000269|PubMed:15152806}.
 -!- SIMILARITY: Belongs to the aromatic prenyltransferase family.
     {ECO:0000305}.
