Asperfuran, a novel antifungal metabolite from Aspergillus oryzae.
Asperfuran is a novel antifungal dihydrobenzofuran derivative produced by a strain of Aspergillus oryzae. Asperfuran weakly inhibited chitin synthase from Coprinus cinereus. This inhibition could be abolished by the addition of egg lecithin. In the agar diffusion assay asperfuran induced morphological changes in Mucor miehei at very low concentrations (20 ng/disc) while growth was only partly i...
متن کاملCarbohydrate binding specificity of a fucose-specific lectin from Aspergillus oryzae: a novel probe for core fucose.
The alpha1,6-fucosyl residue (core fucose) of glycoproteins is widely distributed in mammalian tissues and is altered under pathological conditions. A probe that specifically detects core fucose is important for understanding the role of this oligosaccharide structure. Aleuria aurantia lectin (AAL) and Lens culimaris agglutinin-A (LCA) have been often used as carbohydrate probes for core fucose...
متن کاملPurification, characterization, and substrate specificity of a novel highly glucose-tolerant beta-glucosidase from Aspergillus oryzae.
Aspergillus oryzae was found to secrete two distinct beta-glucosidases when it was grown in liquid culture on various substrates. The major form had a molecular mass of 130 kDa and was highly inhibited by glucose. The minor form, which was induced most effectively on quercetin (3,3',4',5,7-pentahydroxyflavone)-rich medium, represented no more than 18% of total beta-glucosidase activity but exhi...
متن کاملPurification, characterization, and heterologous expression in Fusarium venenatum of a novel serine carboxypeptidase from Aspergillus oryzae.
A novel serine carboxypeptidase (EC 3.4.16.1) was found in an Aspergillus oryzae fermentation broth and was purified to homogeneity. This enzyme has a molecular weight of ca. 67,000, as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and its specific activity is 21 U/mg for carbobenzoxy (Z)-Ala-Glu at pH 4.5 and 25 degrees C. It has a ratio of bimolecular constants for ...
متن کاملA new class of glutaminase from Aspergillus oryzae.
The koji mold Aspergillus oryzae is able to produce glutaminase which converts glutamine to glutamic acid, one of the most important flavor components in soy sauce. We present here the isolation and the complete nucleotide sequence of the glutaminase- encoding gene from A. oryzae U212, an industrial strain used in Thailand. N-terminal and internal amino acid sequences were determined from purif...
