IUBMB Enzyme Nomenclature


Accepted name: chlorogenate—glucarate O-hydroxycinnamoyltransferase

Reaction: chlorogenate + glucarate = quinate + 2-O-caffeoylglucarate

Other name(s): chlorogenate:glucarate caffeoyltransferase; chlorogenic acid:glucaric acid O-caffeoyltransferase; chlorogenate:glucarate caffeoyltransferase

Systematic name: chlorogenate:glucarate O-(hydroxycinnamoyl)transferase

Comments: Galactarate can act as acceptor, more slowly. Involved with EC quinate O-hydroxycinnamoyltransferase in the formation of caffeoylglucarate in tomato.
