Codeine 3-O-demethylase catalyzed biotransformation of morphinan alkaloids in Escherichia coli: site directed mutagenesis of terminal residues improves enzyme expression, stability and biotransformation yield

Journal of Biological Engineering
The cultivation of opium poppy is the only commercially viable source of most morphinan alkaloids. Bioproduction of morphinan alkaloids in recombinant whole-cell systems provides a promising alternate source of these valuable compounds.

The screening of alkaloids from the ethyl acetate extract of Papaver seeds / Nurul Intan Shafinas Md Nasir [PDF]

, 2012
Alkaloids are distinguished into three categories; true alkaloids, protoalkaloids and pseudoalkaloids. In most alkaloids, the backbones are benzylisoquinoline alkaloids.
