Elucidating the enzyme network driving Amaryllidaceae alkaloids biosynthesis in Leucojum aestivum. [PDF]

open access: yesPlant Biotechnol J
Schematic representation of Amaryllidaceae alkaloid biosynthesis in Leucojum aestivum. Norbelladine synthase (LaNBS) and noroxomaritidine/norcraugsodine reductase (LaNRII) catalyze the condensation of tyramine and 3,4‐dihydroxybenzaldehyde to form norbelladine, which is subsequently O‐methylated by norbelladine‐4′‐O‐methyltransferase (LaN4′OMT ...
