Opiate analgesics' dual role in firefly luciferase activity.


The effects of three opiate analgesics, isolated from opium, on the firefly luciferase enzyme have been studied. Morphine (MN), 6-acetylmorphine (MAM), and diacetylmorphine (DAM) inhibited the enzyme activity at different levels. At lower concentrations, MN and MAM enhanced enzyme activity, effecting inhibition at higher concentrations. However, DAM… (More)
