Terephthalate 1,2-dioxygenase (EC 1.14.12.15) is an enzyme that catalyzes the chemical reaction

+ NADH
 
 
O2 + H+
 
 
 
 
3,4-dihydroxycyclohexa-1,5-diene-1,4-dicarboxylic acid
+ NAD+
 

The four substrates of this enzyme are terephthalic acid, reduced nicotinamide adenine dinucleotide (NADH), oxygen, and a proton. Its products are (3S,4R)-3,4-dihydroxycyclohexa-1,5-diene-1,4-dicarboxylic acid and NAD+.[1][2]

This enzyme is an oxidoreductase that uses molecular oxygen as oxidant and incorporates both its atoms into the starting material. The systematic name of this enzyme class is benzene-1,4-dicarboxylate,NADH:oxygen oxidoreductase (1,2-hydroxylating). Other names in common use include benzene-1,4-dicarboxylate 1,2-dioxygenase, and 1,4-dicarboxybenzoate 1,2-dioxygenase. It is a Rieske protein containing an iron–sulfur cluster and participates in the metabolism of terephthalic acid.[1]
