Hydroxycinnamoyl-CoA:shikimate hydroxycinnamoyltransferase, usually abbreviated HCT, is an enzyme involved in the biosynthesis of phenylpropanoid metabolites by plants. It catalyzes reversible formation of an ester bond between shikimate and the CoA thioester forms of various hydroxycinnamic acids, including p-coumaric acid and caffeic acid. HCT is a member of the BAHD family of acyltransferases, a diverse family of enzymes involved in the synthesis of many different classes of plant specialized metabolites. Alternative names of HCT include 4-coumaroyl-CoA O-(hydroxycinnamoyl)transferase, shikimate hydroxycinnamoyltransferase, and shikimate O-hydroxycinnamoyltransferase.

Role in phenylpropanoid biosynthesis

 * hydroxycinnamoyl-CoA + shikimate $$\rightleftharpoons$$ CoA + hydroxycinnamoylshikimate
