Description
The enzyme catalyses a step in prokaryotic ubiquinone biosynthesis, as well as in plastoquinone biosynthesis in cyanobacteria. The enzyme can accept substrates with different polyprenyl tail lengths in vitro, but uses a specific length in vivo, which is determined by the polyprenyl diphosphate synthase that exists in the specific organism. It requires a prenylated flavin cofactor that is produced by EC 2.5.1.129, flavin prenyltransferase
