Beta-carotene biosynthesis in genetically engineered hosts

摘要

DNA segments encoding the Erwinia herbicola enzymes geranylgeranyl pyrophosphate (GGPP) synthase, phytoene synthase, phytoene dehydrogenase- 4H and lycopene cyclase, vectors containing those DNA segments, host cells containing the vectors and methods for producing those enzymes and beta-carotene by recombinant DNA technology in transformed host organisms are disclosed.
