| Enzymatic Synthesis of Quinolizidine Alkaloids in Lupin Chloroplasts  | | | | Abstract
| The enzymatic sequence responsible for the biosynthesis o f tetracyclic quinolizidine alkaloids could be localized in chloroplasts isolated from Lupinus polyphyllus leaves and L. albus seedlings by differential centrifugation. U pon feeding of cadaverine to isolated chloroplasts lupanine is produced as the m ain alkaloid. Chloroplasts treated with digitonine produce sparteine and 17-oxosparteine instead o f lupanine, thus indicating that the biosynthetic sequence is interrupted. The intermediacy of 17-oxosparteine could be confirmed since exogeneous 17-oxosparteine is con verted into lupanine by intact chloroplasts. 17-Oxosparteine synthase (see Z. N aturforsch. 34 c, 704 1979) the key enzyme of quinolizidine alkaloid biosynthesis could be solubilized from chloro plasts treated with detergents or osmotic shock. | | | |
