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.
