| physiological function | the enzyme is bifunctional and shows chlorogenate caffeoyltransferase (CCT) as well as quinate O-hydroxycinnamoyltransferase (HQT, EC 2.3.1.99) activity. The enzyme also has a dual localisation and is active as HQT in the cytosol and as chlorogenate:chlorogenate hydroxycinnamoyltransferase (CCT) in the vacuole. The rather low affinity of CCT towards chlorogenate can be overcome by the high chlorogenic acid concentration usually found in the vacuole | Solanum lycopersicum |
