show Brenda entry

EC number

1.14.12.11

Accepted name

toluene dioxygenase

Reaction

toluene + NADH + H⁺ + O₂ = (1S,2R)-3-methylcyclohexa-3,5-diene-1,2-diol + NAD⁺

Other name(s)

toluene 2,3-dioxygenase

Systematic name

toluene,NADH:oxygen oxidoreductase (1,2-hydroxylating)

CAS registry number

120038-36-0

Comment

A system, containing a reductase which is an iron-sulfur flavoprotein (FAD), an iron-sulfur oxygenase, and a ferredoxin. Some other aromatic compounds, including ethylbenzene, 4-xylene and some halogenated toluenes, are converted into the corresponding cis-dihydrodiols.
