| additional information | enzyme additionally shows N-acetylserotonin methyltransferase activity, reaction of EC 2.1.1.4, and caffeic acid methyltransferase activity, reaction of EC 2.1.1.68. The catalytic efficiency for N-acetylserotonin methyltransferase activity is 709fold lower than for caffeic acid methyltransferase. In vitro, N-acetylserotonin methyltransferase activity is dramatically decreased by the addition of caffeic acid in a dose-dependent manner, but the activity of caffeic acid methyltransferase is not altered by N-acetylserotonin | Arabidopsis thaliana | ? | - |
