ENZYME entry: EC 1.14.13.243

PURL: https://purl.expasy.org/enzyme/EC/1.14.13.243
Accepted Name
toluene 2-monooxygenase
Alternative Name(s)
toluene ortho-monooxygenase
Reaction catalysed
  • toluene + NADH + O2 + H(+) = 2-hydroxytoluene + NAD(+) + H2O
  • 2-hydroxytoluene + NADH + O2 + H(+) = 3-methylcatechol + NAD(+) + H2O
Comment(s)
  • The enzyme, characterized from the bacterium Burkholderia cepacia, belongs to a class of nonheme, oxygen-dependent diiron enzymes.
  • It contains a hydroxylase component with two binuclear iron centers, an NADH-oxidoreductase component containing FAD and a [2Fe-2S] iron- sulfur cluster, and a third component involved in electron transfer between the hydroxylase and the reductase.
  • The enzyme dihydroxylates its substrate in two sequential hydroxylations, initially forming 2-methylphenol, which is hydroxylated to 3-methylcatechol.
