and L. luteus are described. The enzymes catalysing the syntheses of the cinnamic acid O -ester of 13-hydroxylupanine and hydroxycinnamic acid O -esters of lupinine (4-coumaroyl- and feruloyllupinine) are characterized and classified as cinnamoyl-CoA: 13-hydroxylupanine O -cinnamoyltransferase (EC 2.3. 1.-) and hydroxycinnamoyl-CoA: lupinine O -hydroxycinnamoyltransferase (EC 2.3. 1.-).
