trans-1,2-dihydrobenzene-1,2-diol dehydrogenase activity

Definition

Target type: molecularfunction

Catalysis of the reaction: NADP+ + trans-1,2-dihydrobenzene-1,2-diol = NADPH + catechol. [EC:1.3.1.20, MetaCyc:1.3.1.20-RXN]

Trans-1,2-dihydrobenzene-1,2-diol dehydrogenase activity is an enzymatic function that catalyzes the oxidation of trans-1,2-dihydrobenzene-1,2-diol (catechol) to 1,2-benzoquinone. This reaction is a key step in the degradation of aromatic compounds, including benzene, toluene, and xylene, by many microorganisms. The enzyme uses NAD+ as an electron acceptor and transfers two electrons from the substrate to the coenzyme, reducing NAD+ to NADH. The active site of the enzyme typically contains a flavin adenine dinucleotide (FAD) cofactor, which acts as a transient electron carrier between the substrate and NAD+. Trans-1,2-dihydrobenzene-1,2-diol dehydrogenase activity is essential for the detoxification of aromatic compounds and plays a crucial role in the bioremediation of polluted environments. The enzyme is also involved in the biosynthesis of various secondary metabolites, including pigments and antibiotics, in some organisms.'
