DISTRIBUTION OF 1-SINAPOYLGLUCOSE:CHOLINE SINAPOYLTRANSFERASE ACTIVITY IN THE BRASSICACEAE

Article abstract of DOI:10.1016/S0031-9422(00)80736-0

The occurence of 1-sinapoylglucose:choline sinapoyltransferase (SCT) in seeds of various members of the Brassicaceae is reported.Within the species and cultivars investigated, a positive correlation was found between extractable levels of enzyme activity and the degree of sinapine accumulation.High enzymatic activities were found in seeds from Brassica, Raphanus and Sinapis, known for their high sinapine content.Key Word Index - Brassica; Raphanus; Sinapis; Brassicaceae; phenylpropanoid metabolism; hydroxycinnamic acid ester; glucose ester; sinapine; 1-sinapoylglucose; choline sinapoyltransferase; transacylase.
