Formation of a complex pattern of sinapate esters in Brassica napus seeds, catalyzed by enzymes of a serine carboxypeptidase-like acyltransferase family?

Structures of 15 seed constituents of oilseed rape were identified by spectroscopic methods. RNAi-based suppression of a sinapate glucosyltransferase gene (BnSGT1) resulted in the disappearance or marked decrease of various sinapate esters indicating that they are synthesized via 1-O-sinapoyl-β-glucose assumed to be catalyzed by a SCPL acyltransferase protein family.
