IntEnz Enzyme Nomenclature


Accepted name:
quinate O-hydroxycinnamoyltransferase
Other name:
hydroxycinnamoyl coenzyme A-quinate transferase
Systematic name:
feruloyl-CoA:quinate O-(hydroxycinnamoyl)transferase



Caffeoyl-CoA and 4-coumaroyl-CoA can also act as donors, but more slowly. Involved in the biosynthesis of chlorogenic acid in sweet potato and, with EC chlorogenate-glucarate O-hydroxycinnamoyltransferase, in the formation of caffeoyl-CoA in tomato.
