In enzymology, a quinate O-hydroxycinnamoyltransferase (EC 2.3.1.99) is an enzyme that catalyzes the chemical reaction
- feruloyl-CoA + quinate CoA + O-feruloylquinate
Thus, the two substrates of this enzyme are feruloyl-CoA and quinate, whereas its two products are CoA and O-feruloylquinate.
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 feruloyl-CoA:quinate O-(hydroxycinnamoyl)transferase. This enzyme is also called hydroxycinnamoyl coenzyme A-quinate transferase. This enzyme participates in phenylpropanoid biosynthesis.
