Biosynthesis of Ascorbic Acid
hypophosphite for the conversion of D-glucuronolactone into L-ascorbic acid. 9. The presence of borate or Antabuse, each at mm-concentration, inhibits the conversion of Dglucuronolactone into L-ascorbic acid to about 50 %. 10. The optimum conditions for the action of the enzyme system have been studied. 11. The biosynthesized ascorbic acid has been identified by paper chromatography and by a bi...
متن کاملBiosynthesis of aspergillic acid.
of aspergillic acid from isoleucine in replacement cultures (3), there has been no work reported previously on the biogenesis of this antibiotic. In the present work, A. flavus was grown on a medium containing radioactive leucine or isoleucine, and these compounds were found to be incorporated into the aspergillic acid formed. Aspergillic acid was degraded to determine what part of the molecule...

15 صفحه اولBiosynthesis of terpenoid natural products in fungi.
Tens of thousands of terpenoid natural products have been isolated from plants and microbial sources. Higher fungi (Ascomycota and Basidiomycota) are known to produce an array of well-known terpenoid natural products, including mycotoxins, antibiotics, antitumor compounds, and phytohormones. Except for a few well-studied fungal biosynthetic pathways, the majority of genes and biosynthetic pathw...
