DE   toluene 2-monooxygenase.
AN   toluene ortho-monooxygenase.
CA   (1) H(+) + NADH + O2 + toluene = 2-hydroxytoluene + H2O + NAD(+).
CA   (2) 2-hydroxytoluene + H(+) + NADH + O2 = 3-methylcatechol + H2O +
CA   NAD(+).
CC   -!- The enzyme, characterized from the bacterium Burkholderia cepacia,
CC       belongs to a class of nonheme, oxygen-dependent diiron enzymes.
CC   -!- It contains a hydroxylase component with two binuclear iron centers,
CC       an NADH-oxidoreductase component containing FAD and a [2Fe-2S] iron-
CC       sulfur cluster, and a third component involved in electron transfer
CC       between the hydroxylase and the reductase.
CC   -!- The enzyme dihydroxylates its substrate in two sequential
CC       hydroxylations, initially forming 2-methylphenol, which is
CC       hydroxylated to 3-methylcatechol.
