The enzymes were classified as coenzyme A (CoA)-ester-dependent acyltransferases (EC 2.3.1), i.e. hydroxycinnamoyl-CoA:meso-tartrate hydroxycinnamoyltransferase (CTT), hydroxycinnamoyl-CoA:caf-feoyl-meso-tartrate hydroxycinnamoyltransferase (CCT), hydroxycinnamoyl-CoA:shikimate hydroxycinnamoyltransferase (CST), and hydroxycinnamoyl-CoA:quinate hydroxycinnamoyltransferase. The CTT, CCT, and CST were partially purified and separated from E. arvense gametophytes by hydrophobic interaction chromatography on Fractogel TSK Butyl-650 followed by molecular exclusion on fast protein liquid chromatography-Superdex-75 with 87-, 62-, and 130- fold enrichments and 12, 8, and 11% yields, respectively.
