In enzymology, a shikimate O-hydroxycinnamoyltransferase () is an enzyme that catalyzes the chemical reaction 4-coumaroyl-CoA + shikimate CoA + 4-coumaroylshikimate Thus, the two substrates of this enzyme are 4-coumaroyl-CoA and shikimate, whereas its two products are CoA and 4-coumaroylshikimate. This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is 4-coumaroyl-CoA:shikimate O-(hydroxycinnamoyl)transferase. This enzyme is also called shikimate hydroxycinnamoyltransferase. This enzyme participates in phenylpropanoid biosynthesis. References EC 2.3.1 Enzymes of unknown structure Hydroxycinnamic acids metabolism
