EC 4.1.1.98 Details
EC number
4.1.1.98
Accepted name
4-hydroxy-3-polyprenylbenzoate decarboxylase
Reaction
a 4-hydroxy-3-polyprenylbenzoate = a 2-polyprenylphenol + CO2
Other name(s)
ubiD (gene name), 4-hydroxy-3-solanesylbenzoate decarboxylase, 3-octaprenyl-4-hydroxybenzoate decarboxylase
Systematic name
4-hydroxy-3-polyprenylbenzoate carboxy-lyase
Comment
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.
