WebJul 5, 2015 · Morphinan biosynthesis requires the isomerization of ( S )- to ( R )-reticuline. The gene STORR (named for “ ( S )- to ( R )-reticuline”) is only found in poppy species that produce morphinans. STORR evolved with two other genes that result in morphine production. The resulting gene fusion plays a key role in production of morphine. happy hearts first aidWebMay 30, 2013 · MORPHINE. 1.
