Function
Component of the terephthalate 1,2-dioxygenase multicomponent enzyme system which catalyzes the dioxygenation of terephthalate (TER/TPA) to 1,2-dihydroxy-3,5-cyclohexadiene-1,4-dicarboxylic acid (DCD). It can also use 2,5-dicarboxypyridine (PDC) and 1,4-napthalenedicarboxylic acid (NDC) as substrates, and preferentially uses NADPH which is the physiological electron donor.
