Stereospecific studies on carotenoid biosynthesis.
Various species of [2-14C] MVA stereospecifically labelled with tritium at C-2, C-4 and C-5 have been used to study details of carotenoid biosynthesis in a variety of preparations including chioroplasts, fruit and root slices, and fungi. Mechanisms have been proposed for the dimerization of geranylgeranyl pyrophosphate to form phytoene, for the cyclization of acyclic precursors to form aand a-c...
متن کاملRecent Studies of Carotenoid Biosynthesis
The effects of nicotine on carotenoid biosynthesis have been investigated in a non-photosynthetic Flavobacterium strain 0147, and in two photosynthetic bacteria, Rhodopseudomonas spheroides and Rhodomicrobium vanrtielii. In Flavobacterium, nicotine inhibits the synthesis of the nOrmal main carotenoid, zeaxanthin, and causes an accumulation of lycopene at high nicotine concentration, and rubixan...
متن کاملCarotenoid Biosynthesis in Fusarium
Many fungi of the genus Fusarium stand out for the complexity of their secondary metabolism. Individual species may differ in their metabolic capacities, but they usually share the ability to synthesize carotenoids, a family of hydrophobic terpenoid pigments widely distributed in nature. Early studies on carotenoid biosynthesis in Fusariumaquaeductuum have been recently extended in Fusarium fuj...
متن کاملSome studies on carotenoid synthesis.
INTRODUCTION Traditionally synthesis is invoked as the final proof of a structure deduced by other means. In the carotenoid field synthesis is being used increasingly as an integral part of structural studies in order to elucidate some molecular feature for which the other evidence is inconclusive or ambiguous. Synthesis also fulfils the very important role of making many carotenoids much more ...
متن کاملCarotenoid Biosynthesis—the Early Steps
This paper describes recent biosynthetic and enzymological studies from a number of laboratories and relates them to our current understanding of the pathways of carotenoid formation. A number of problems concerning phytoene biosynthesis and dehydrogenation are discussed and the work of our own laboratory on the biosynthesis of the triterpenoid carotenoids is reviewed.
