A cell-free system of Papaver somniferum has been isolated, capable of synthesizing norlaudanosoline-1-carboxylic acid, dehydronorlaudanosoline, and norlaudanosoline from 3,4-dihydroxyphenethylamine (dopamine) and 3,4-dihydroxyphenylpyruvic acid. The enzyme activity lies in a Triton X-100 solubilized protein fraction.
