Reaction: asperlicin C + NAD(P)H + H+ + O2 = asperlicin E + NAD(P)+ + H2O
Other name(s): AspB
Systematic name: asperlicin C,NAD(P)H:oxygen oxidoreductase
Comments: The enzyme, characterized from the fungus Aspergillus alliaceus, contains an FAD cofactor. The enzyme inserts a hydroxyl group, leading to formation of a N-C bond that creates an additional cycle between the bicyclic indole and the tetracyclic core moieties, resulting in the heptacyclic asperlicin E.
