Enzymatic Synthesis of Carotenes
The pathway of carotene biosynthesis from isopentenyl pyrophosphate in tomato fruit plastids has been established, except for minor details, through the conversion of radioactive sub— strates and intermediates to acyclic and cyclic carotenes in cell—free systems. After the pathway of carotene biosynthesis was established attention was turned to the isola— tion and purification of enzymes of car...
متن کاملEnzymatic synthesis of carotenes and related compounds.
Data are presented in this paper which establish many of the reactions involved in the biosynthesis of carotenes. Studies have shown that all of the enzymes required for the synthesis of acyclic and cyclic carotenes from mevalonic acid are present in plastids of tomato fruits. Thus, it has been demonstrated that a soluble extract of an acetone powder of tomato fruits converts mevalonic acid to ...
