Abstract
Disclosed are methods for converting a first morphinan alkaloid compound into a second morphinan alkaloid compound in the presence of a neopinone isomerase enzyme under reaction conditions permitting the conversion of the first alkaloid compound into the second alkaloid compound. The first alkaloid compound can be neopinone or neomorphinone. The second alkaloid compound can be codeinone or morphinone. Related compositions are also disclosed.
