EC 1.14.13.244

Accepted name: phenol 2-monooxygenase (NADH)

Reaction: phenol + NADH + H+ + O2 = catechol + NAD+ + H2O

Other name(s): dmpLMNOP (gene names)

Systematic name: phenol,NADH:oxygen oxidoreductase (2-hydroxylating)

Comments: The enzyme, characterized from the bacteria Pseudomonas sp. CF600 and Acinetobacter radioresistens, consists of a multisubunit oxygenease component that contains the active site and a dinuclear iron center, a reductase component that contains FAD and one iron-sulfur cluster, and a regulatory component. The reductase component is responsible for transferring electrons from NADH to the dinuclear iron center.
