Characterization of cinnamate 4-hydroxylase (CYP73A) and p-coumaroyl 3'-hydroxylase (CYP98A) from Leucojum aestivum, a source of Amaryllidaceae alkaloids.

Plant physiology and biochemistry : PPB
Biosynthesis of Amaryllidaceae alkaloids (AA) starts with the condensation of tyramine with 3,4-dihydroxybenzaldehyde. The latter derives from the phenylpropanoid pathway that involves modifications of trans-cinnamic acid, p-coumaric acid, caffeic acid ...
