 Title    Enzymic Synthesis of Hydroxycinnamic Acid Esters of Glucaric Acid and Hydroaromatic Acids from the Respective l-O-Hydroxycinnamoylglucoside and Hydroxycinnamoyl-Coenzyme A Thioester as Acyldonors with a Protein Preparation from Cestrum elegáns Leaves  
 Abstract    Hydroxycinnamoyltransferase activities which catalyze the formation of O-hydroxycinnamoyl-(p-coumaroyl-, feruloyl-, and sinapoyl-)-glucaric acids via the corresponding 1-O-hydroxycin-namoyl-ß-glucoses, and 0-(p-coumaroyl)-quinic acid and 0-(p-coumaroyl)-shikimic acid both via p-coumaroyl-CoA thioester have been isolated from leaves of Cestrum elegáns D. F. L. v. Schlechtendal. The enzymic activities involved could be classified as 1-O-hydroxycinnamoyl-ß-glucose : glucaric acid hydroxycinnamoyltransferase (EC 2.3.1.-) and /?-coumaroyl-CoA : quinic acid/shikimic acid hydroxycinnamoyltransferase (EC 2.3.1. —). This is the first time that both the O-glucoside-and the S-CoA-dependent activities in phenolic acid-ester formation were found to be present in the same plant.
