ID 1.14.14.21 DE dibenzothiophene monooxygenase. CA dibenzothiophene + 2 FMNH2 + 2 O2 = dibenzothiophene 5,5-dioxide + 2 FMN CA + 2 H(+) + 2 H2O. CC -!- This bacterial enzyme catalyzes the first two steps in the CC desulfurization pathway of dibenzothiophenes, the oxidation of CC dibenzothiophene into dibenzothiophene sulfone via dibenzothiophene- CC 5-oxide. CC -!- The enzyme forms a two-component system with EC 1.5.1.42, which also CC interacts with EC 1.14.14.22.
