A heartwood norlignan, (E)-hinokiresinol, is formed from 4-coumaryl 4-coumarate by a Cryptomeria japonica enzyme preparation

An enzyme preparation from the cultured cells of Cryptomeria japonica catalyses the formation of a heartwood norlignan, (E)-hinokiresinol, from two distinct phenylpropanoid monomers: 4-coumaroyl CoA and 4-coumaryl alcohol, and from a dimer: 4-coumaryl 4-coumarate.
