Cyclopiazonic Acid Biosynthesis of Aspergillus flavus and Aspergillus oryzae
Cyclopiazonic acid (CPA) is an indole-tetramic acid neurotoxin produced by some of the same strains of A. flavus that produce aflatoxins and by some Aspergillus oryzae strains. Despite its discovery 40 years ago, few reviews of its toxicity and biosynthesis have been reported. This review examines what is currently known about the toxicity of CPA to animals and humans, both by itself or in comb...
متن کاملExtracellular acid protease of Aspergillus oryzae grown on liquid media: multiple forms due to association with heterogeneous polysaccharides.
The acid protease (EC 2.4.23.6) that is produced extracellularly when Aspergillus oryzae is grown on liquid media has been isolated and characterized. The enzyme was purified by precipitation with tannic acid, chromatography on Duolite A-2, and gel filtration on Sephadex G-100. The last step yielded four active components, with varying molecular weights ranging from 42,000 to 60,000. Two of the...
متن کاملElectrophoretic Separation of Multiple Forms of Particle Associated Acid Phosphatase.
A considerable body of evidence supports the contention that much, if not all, cellular acid phosphatase is contained within particles designated as IYSOsomes (deDuve, 1959; Novikoff, 1961). Release of the enzyme from these particles is effected by conditions that destroy the integrity of the lysosomal membrane. Often a discrepancy is found between the total activity of acid phosphatase and the...
متن کاملExtraction of milk-clotting enzyme produced by solid state fermentation of Aspergillus oryzae.
Studies on the extraction of milk-clotting enzyme after solid-state fermentation (SSF) of wheat bran by a local strain of Aspergillus oryzae LS1 were done. The extraction of the enzyme was found to be depended on different parameters like nature of extractant, soaking time, temperature etc. From different inorganic and organic extractants, calcium chloride (0.05%) and glycerol (40%) were found ...
متن کاملFunctional analysis of fructosyl-amino acid oxidases of Aspergillus oryzae.
Three active fractions of fructosyl-amino acid oxidase (FAOD-Ao1, -Ao2a, and -Ao2b) were isolated from Aspergillus oryzae strain RIB40. N-terminal and internal amino acid sequences of FAOD-Ao2a corresponded to those of FAOD-Ao2b, suggesting that these two isozymes were derived from the same protein. FAOD-Ao1 and -Ao2 were different in substrate specificity and subunit assembly; FAOD-Ao2 was act...
