Carbazole 19a-dioxygenase (EC 1.14.12.22 CARDO) is an enzyme with system name 9H-carbazoleNAD(P)H:oxygen oxidoreductase (23-hydroxylating). This enzyme catalyses the following chemical reaction 9H-carbazole + NAD(P)H + H+ + O2 2′-aminobiphenyl-23-diol + NAD(P)+Carbazole 19a-dioxygenase catalyses the first reaction in the pathway of carbazole degradation.
