From Wikipedia, the free encyclopedia
Hydroquinone 1,2-dioxygenase (
EC
1.13.11.66 , hydroquinone dioxygenase ) is an
enzyme with
systematic name benzene-1,4-diol:oxygen 1,2-oxidoreductase (decyclizing) .
[1]
[2]
[3] This enzyme
catalyses the following
chemical reaction
benzene-1,4-diol + O2
⇌
{\displaystyle \rightleftharpoons }
(2E,4Z)-4-hydroxy-6-oxohexa-2,4-dienoate
The enzyme is an
extradiol -type dioxygenase. It belongs to the nonheme-iron(II)-dependent dioxygenase family.
