| Chloroplast Autonomy in Acetyl-Coenzyme-A-Formation and Terpenoid Biosynthesis  | | | | Abstract
| Isolated intact spinach chloroplasts were supplied with 14C-labeled C 0 2, phosphoglycerate, phos-phoenolpyruvate, acetate and mevalonate and the incorporation o f radioactivity into /?-carotene and plastoquinone-9 assayed. All applied substrates were capable of crossing the chloroplast envelope. Except phosphoenolpyruvate all radioactive precursors were incorporated into ß-carotene and also into plastoquinone-9. It is concluded that spinach chloroplasts are autonom in acetyl-coenzyme-A-formation and terpenoid biosynthesis. There is a direct carbon flow from intermediates of the Calvin-cycle via acetyl-coenzyme-A and mevalonic acid existing in the chlo roplast leading to the carotenoids and isoprenoid side-chains o f chlorophylls and quinones. | | | |
