Omega-hydroxypalmitate O-feruloyl transferase (, hydroxycinnamoyl-CoA omega-hydroxypalmitic acid O-hydroxycinnamoyltransferase, HHT) is an enzyme with systematic name feruloyl-CoA:16-hydroxypalmitate feruloyltransferase. This enzyme catalyses the following chemical reaction
p-Coumaroyl-CoA and sinapoyl-CoA also act as substrates.
