Eschscholtzia tenuifolia

SCHUMACHER, H.-M., RUFFER, M., NAGAKURA, N ZENK, M.H., Partial purification and properties of (5)-norlaudanosoline synthase from Eschscholtzia tenuifolia cell cultures. Planta Med., 1983, 48,212-220. 

As another example of the value of enzymological studies, the major enzymes of the benzylisoquinoline alkaloid pathway have also been isolated from plant tissue culture and studied by Zenk and co-workers (see Chapter 34) (Fig. 1.2). An enzyme, (S)-norlaudanosoline synthase, which catalyzes the conversion of dopamine and (3,4-dihydroxyphen-yl)acetaldehyde (9) into (S)-norlaudanosoline (10) has been purified about 40-fold from cell suspension cultures of Eschscholtzia tenuifolia (see also cluster 32 for up-dated in-...
