-
the enzyme catalyzes the monooxygenation of anthranoyl-CoA to 5-hydroxyl-2-aminobenzoyl-CoA and the subsequent reduction to the dearomatized product 2-amino-5-oxo-cyclohex-1-ene-1-carbonyl-CoA. The two reactions occur in separate domains, termed the monooxygenase and reductase domain. Binding studies with 2-aminobenzoyl-CoA and p-hydroxybenzaldehyde as probes for the monooxygenase and reductase domain, respectively, indicate that two functionally distinct and independent active sites exist
