Territrems, tremorgenic mycotoxins of Aspergillus terreus.
The tremorgenic mycotoxins isolated from Aspergillus terreus were given the trivial names territrem A and B instead of their previous designations of C1 and C2 respectively. High-resolution mass spectral data suggested the molecular formula of territrem A to be C28H30O9 and that of territrem B,C29H34O9. They were partially characterized by ultraviolet, infrared, proton magnetic resonance, and m...
متن کاملLovastatin biosynthesis by Aspergillus terreus in a chemically defined medium.
Lovastatin is a secondary metabolite produced by Aspergillus terreus. A chemically defined medium was developed in order to investigate the influence of carbon and nitrogen sources on lovastatin biosynthesis. Among several organic and inorganic defined nitrogen sources metabolized by A. terreus, glutamate and histidine gave the highest lovastatin biosynthesis level. For cultures on glucose and ...
متن کاملMevinolinic acid biosynthesis by Aspergillus terreus and its relationship to fatty acid biosynthesis.
Mevinolinic acid, the open acid form of mevinolin, which is a metabolite of Aspergillus terreus, has been shown to be a competitive inhibitor of the enzyme 3-hydroxy-3-methylglutaryl coenzyme A reductase (Alberts et al., Proc. Natl. Acad. Sci. U.S.A. 77:3957-3961, 1980). The biosynthesis of mevinolinic acid was studied by examining the incorporation of [1-14C]acetate and [methyl-14C]methionine ...
متن کاملMicrobial transformation of artemisinin by Aspergillus terreus
BACKGROUND Artemisinin (1) and its derivatives are now being widely used as antimalarial drugs, and they also exhibited good antitumor activities. So there has been much interest in the structural modification of artemisinin and its derivatives because of their effective bioactivities. The microbial transformation is a promising route to obtain artemisinin derivatives. The present study focuses...
متن کاملExpression of the Aspergillus terreus itaconic acid biosynthesis cluster in Aspergillus niger
BACKGROUND Aspergillus terreus is a natural producer of itaconic acid and is currently used to produce itaconic acid on an industrial scale. The metabolic process for itaconic acid biosynthesis is very similar to the production of citric acid in Aspergillus niger. However, a key enzyme in A. niger, cis-aconitate decarboxylase, is missing. The introduction of the A. terreus cadA gene in A. niger...
