IUBMB Enzyme Nomenclature


Accepted name: quinate O-hydroxycinnamoyltransferase

Reaction: feruloyl-CoA + quinate = CoA + O-feruloylquinate

Other name(s): hydroxycinnamoyl coenzyme A-quinate transferase

Systematic name: feruloyl-CoA:quinate O-(hydroxycinnamoyl)transferase

Comments: 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.
