This domain is found on aromatic hydroxylating enzymes such as 2-oxo-1,2-dihydroquinoline 8-monooxygenase from Pseudomonas putida and carbazole 1,9a-dioxygenase from Janthinobacterium. These enzymes are homotrimers and are distantly related to the typical oxygenase [2]. This domain is found C terminal to the Rieske domain which binds an iron-sulphur cluster.	Domain
