CC   -!- FUNCTION: Hydroxycinnamoyl transferase that catalyzes in vitro the
CC       transfer of an acyl from p-coumaryol-CoA to glycerol or shikimate, to
CC       produce 2-O-p-coumaroyl glyceride or coumaroyl shikimate, respectively.
CC       Quercetin, glutarate, or malate do not serve as acyl acceptors in
CC       vitro. Can use feruloyl-CoA and caffeoyl-CoA as acyl donors.
