Plays a major role in the degradation of chloroaromatic compounds by channeling maleylacetate and some of its substituted derivatives into the 3-oxoadipate pathway. This enzyme converts maleylacetate and 2-chloromaleylacetate with similar efficiencies. 3-oxoadipate + NAD(+) = H(+) + maleylacetate + NADH 3-oxoadipate + NADP(+) = H(+) + maleylacetate + NADPH Aromatic compound metabolism; 3-chlorocatechol degradation. Belongs to the iron-containing alcohol dehydrogenase family.
