WebSep 21, 2004 · The question of the origin of endogenous morphine in animals and humans can be answered only by demonstrating that the morphine molecule is biosynthesized de novo by mammals from distant precursors. In the plant kingdom, the biosynthesis of morphine has been established starting from two molecules of l -tyrosine ( 13 ). WebCreatine kinase B (CK-B) is a key enzyme involved in brain energy metabolism. CK-B also corresponds to the imidazoline-binding protein I2 which binds dopamine (a precursor of morphine biosynthesis) irreversibly. Using biochemical approaches, we show that recombinant mouse CK-B possesses a μM affinity for morphine and binds to morphine …
