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.
