additional information the enzyme also forms beta-caryophyllene via (Z,E)-germacradienyl cation and (E,E)-humulyl cation intermediates. The product profile of the VvShirazTPS-Y2 reaction includes alpha- and beta-cubebene, alpha-copaene, isocaryophyllene, alpha-caryophyllene, (+)-delta-cadinene, cadina-1,4-diene, and caryophyllene oxide, overview. The major products are isocaryophyllene and beta-cubenene Vitis vinifera ?
