induction and repression of amidase enzymes in aspergillus nidulans.aspergillus nidulans can grow on acetamide as both a carbon and nitrogen source and can also grow on formamide as a nitrogen source. two distinct enzymes, an acetamidase and a formamidase, are produced. the control of the synthesis of these two enzymes in a wild-type strain was investigated. the formamidase is induced by acetamide and formamide and repressed by ammonia. the acetamidase is induced by formamide and acetamide, repressed by carbon metabolites derived from glucose and acetate, and re ...19705432013

hyphal wall synthesis in aspergillus nidulans: effect of protein synthesis inhibition and osmotic shock on chitin insertion and morphogenesis.pulse-labeling with n-[acetyl-(3)h] glucosamine and radioautography were used to follow the sites of chitin incorporation in hyphae of an aspergillus nidulans mutant blocked in amino sugar synthesis. growing hyphae incorporated n-acetylglucosamine almost exclusively at the tip. cycloheximide addition greatly increased the label in subapical regions of the hyphae and reduced that at the tip. this effect of cycloheximide was immediate, could be reversed by removing the inhibitor, and did not appea ...19715001195

characterization of the reduced nicotinamide adenine dinucleotide phosphate-nitrate reductase of aspergillus nidulans.the reduced nicotinamide adenine dinucleotide phosphate (nadph)-nitrate oxidoreductase (ec from aspergillus nidulans was purified over 200-fold by use of salt fractionation, gel filtration, and ion-exchange chromatography. the purified enzyme was specific for nadph and catalyzed reduction of nitrate, cytochrome c from isolated mitochondria of aspergillus, and mammalian cytochrome c. an s(0.725) (20, w) of 7.8 was derived with sucrose density gradient centrifugation, and a stokes radius ...19714396143
attempts to detect an alternative vital role for the reduced nicotinamide adenine dinucleotide phosphate-nitrate reductase structural gene in aspergillus nidulans.a possible alternate vital role of the structural gene for reduced nicotinamide adenine dinucleotide phosphate-nitrate reductase in aspergillus nidulans was tested for and found to be absent in a significant number of haploid and diploid strains.19714397637
relationship between energy substrate utilization and specific growth rate in aspergillus nidulans.the maintenance coefficient of glucose-limited aspergillus nidulans chemostat cultures at 30 c was 0.018 g per g (dry weight) per hr for glucose and 0.55 mmoles per g (dry weight) per hr for oxygen. these values can only be approximate because melanin was produced by the mold at low growth rates and because it is unlikely that this polymer contributed to the maintenance energy requirement although it contributed to the dry weight. biomass (defined here as dry weight minus melanin) was used to ca ...19714399338

model for branch initiation in aspergillus nidulans based on measurements of growth parameters.the rate of hyphal elongation and the number of branches per hypha were measured on short sporelings of aspergillus nidulans growing at different rates. the rate of elongation was proportional to total length in unbranched and branched hyphae. at each growth rate, the number of branches per hypha increased with increasing length and gave approximately straight-line graphs when plotted against length. the average number of branches per unit of hyphal length was quite different for the various gro ...19724551743
purification and characterization of acid phosphatase v from aspergillus nidulans.acid phosphatase v of aspergillus nidulans was purified by ammonium sulfate precipitation, gel filtration, and ion-exchange chromatography. the enzyme demonstrated a charge microheterogeneity on starch and acrylamide gel electrophoresis, but proved to be homogeneous on ultracentrifugation and gel filtration. phosphatase v was found to be a classic acid orthophosphoric monoester phosphohydrolase, and it cleaved p-nitrophenylphosphate, glucose-6-phosphate, and uridine-5'-monophosphate at maximal r ...19724552990

mutants with altered glucose repression of amidase enzymes in aspergillus nidulans.aspergillus nidulans produces acetamidase and formamidase enzymes. the acetamidase is produced in reduced amounts during growth on glucose, whereas the formamidase is not greatly affected. mutations in a gene, amdt, which affect glucose repression of amidases are described. one of these, amdt102, causes the acetamidase to be no longer subject to glucose repression and also affects ability to synthesize formamidase. the other, amdt19, results in both the formamidase and the acetamidase being subj ...19724559822
