IntEnz Enzyme Nomenclature
EC 4.1.1.98

Names

Accepted name:
4-hydroxy-3-polyprenylbenzoate decarboxylase
Other names:
ubiD (gene name)
4-hydroxy-3-solanesylbenzoate decarboxylase
3-octaprenyl-4-hydroxybenzoate decarboxylase
Systematic name:
4-hydroxy-3-polyprenylbenzoate carboxy-lyase

Reaction

Comments:

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.
