 Title    Two New Enzymes of Rosmarinic Acid Biosynthesis from Cell Cultures of Coleus blumei: Hydroxyphenylpyruvate Reductase and Rosmarinic Acid Synthase  
 Abstract    Rosmarinic acid biosynthesis can be stimulated in cell cultures of Coleus blumei by culturing the cells in medium with 4% sucrose. In enzyme extracts of these cells two new enzymes of rosmarinic acid biosynthesis were discovered. Hydroxyphenylpyruvate reductase reduces 4-hydroxyphenyl-pyruvate and 3,4-dihydroxyphenylpyruvate to 4-hydroxyphenyllactate and 3,4-dihydroxyphenyl-lactate, respectively, using NADH. Rosmarinic acid synthase transfers the caffeoyl moiety of caffeoyl-CoA to the non-phenolic OH-group of 3,4-dihydroxyphenyllactic acid, in course of which rosmarinic acid is formed.
