Summary:
Like hydroxycinnamic acid serotonin amides (hydroxycinnamic acid serotonin amides biosynthesis), hydroxycinnamic acid tyramine amides belong to the larger group of N-hydroxycinnamic acid amides (HCAAs). HCAAs are synthesized by the condensation of hydroxycinnamoyl-CoA thioesters and aromatic amines. The hydroxycinnamoyl-CoA thioesters include cinnamoyl-CoA, p-coumaroyl-CoA, caffeoyl-CoA, feruloyl-CoA and sinapoyl-CoA. The aromatic amines include tyramine, octopamine, tryptamine, serotonin, dopamine and noradrenaline. The biosynthesis of HCAAs of tyramine is catalyzed by tyramine N-hydroxycinnamoyltransferase (THT).

Hydroxycinnamic acid tyramine amides are wide-spread in higher plants. They are frequently found insoluble constituents of the cell wall. Incorporation of hydroxycinnamic acid tyramine amides into cell wall is believed to enhance the efficiency of cell all to act as a barrier against pathogens by increasing the rigidity and decreasing the digestibility of the cell wall. In agreement with their proposed roles, the potato THT activity was shown increase upon pathogen (P. infestans) infection, and also increase in wounded tuber [Schmidt99].
