title: Carotenoid biosynthesis and biotechnological application.
abstract: A survey is given on the carotenoid biosynthetic pathway leading to beta-carotene and its oxidation products in bacteria and plants. This includes the synthesis of prenyl pyrophosphates via the mevalonate or the 1-deoxyxylulose-5-phosphate pathways as well as the reaction sequences of carotenoid formation and interconversion together with the properties of the enzymes involved. Biotechnological application of this knowledge resulted in the development of heterologous carotenoid production systems using bacteria and fungi with metabolic engineered precursor supply and crop plants with manipulated carotenoid biosynthesis. The recent developments in engineering crops with increased carotenoid contents are covered.
