Compound as reactive (1)

NAD(P)+ + 3,4-dihydroxy-2-methyl-4-farnesyl-3H-quinolin-1-ium-1-olate ← NAD(P)H + 4-hydroxy-2-methyl-3-oxo-4-farnesyl-3,4-dihydroquinoline-1-oxide + H⁺

Compound as product (2)

4-hydroxy-2-methyl-4-[(2E,6E)-3,7,11-trimethyldodeca-2,6,10-trien-1-yl]quinolin-3(4H)-one 1-oxide → 4-hydroxy-2-methyl-3-oxo-4-farnesyl-3,4-dihydroquinoline-1-oxide

NAD(P)H + aurachin C + H⁺ + oxygen → H₂O + NAD(P)+ + 4-hydroxy-2-methyl-3-oxo-4-farnesyl-3,4-dihydroquinoline-1-oxide

Reversible reaction (1)

H₂O + aurachin B + NAD⁺ ↔ NADH + 4-hydroxy-2-methyl-3-oxo-4-farnesyl-3,4-dihydroquinoline-1-oxide + H⁺
