2.3.1.324 |
| Accepted name: |
chlorogenate caffeoyltransferase |
| Reaction: |
2 chlorogenate = 3,5-dicaffeoylquinate + quinate |
| Other name(s): |
CCT (gene name) |
| Systematic name: |
chlorogenate:chlorogenate 3-O-caffeoyltransferase |
| Comments: |
The enzyme has been purified from Solanum lycopersicum (tomato) fruits. In the vacuole, at pH 4-5, it produces 3,5-dicaffeoylquinic acid from cholorgenic acid. In the cytoplasm, at pH 6-7, it can use aromatic acyl-CoAs as donors and catalyses the reaction of EC 2.3.1.99 (quinate O-hydroxycinnamoyltransferase). The initial product, 3,5-dicaffeoylquinic acid, undergoes spontaneous acyl migration to form 4,5-dicaffeoylquinic acid. Small amounts of 1,5-dicaffeoylquinic acid are formed as a byproduct. |
