characterization of the reduced nicotinamide adenine dinucleotide phosphate-nitrate reductase of aspergillus nidulans.the reduced nicotinamide adenine dinucleotide phosphate (nadph)-nitrate oxidoreductase (ec 1.6.6.2) 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

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

regulation of sulfate transport in filamentous fungi.inorganic sulfate enters the mycelia of aspergillus nidulans, penicillium chrysogenum, and penicillium notatum by a temperature-, energy-, ph-, ionic strength-, and concentration-dependent transport system ("permease"). transport is unidirectional. in the presence of excess external sulfate, atp sulfurylase-negative mutants will accumulate inorganic sulfate intracellularly to a level of about 0.04 m. the intracellular sulfate can be retained against a concentration gradient. retention is not ene ...197016657536
action spectra for photosystems i and ii in formaldehyde fixed algae.action spectra were obtained for photosystems i and ii in chemically fixed algal cells and for photosystem i in unfixed lysozyme treated cells. untreated algal cells yielded neither of the 2 light reactions with the reaction mixtures used. the action spectra for photosystem i in the blue-green alga anacystis nidulans and red alga porphyridium cruentum follow the absorption spectrum of chlorophyll a with a small peak in the region of the accessory pigments. in the green alga chlorella pyrenoidosa ...196916657098

regulation of synthesis of glutamate dehydrogenase and glutamine synthetase in micro-organisms.1. aspergillus nidulans, neurospora crassa and escherichia coli were grown on media containing a range of concentrations of nitrate, or ammonia, or urea, or l-glutamate, or l-glutamine as the sole source of nitrogen and the glutamate dehydrogenate and glutamine synthetase of the cells measured. 2. aspergillus, neurospora and escherichia coli cells, grown on l-glutamate or on high concentrations of ammonia or on high concentrations of urea, possessed low glutamate dehydrogenase activity compared ...19694901826

evidence against necessary phosphorylation during hexose transport in aspergillus nidulans.the transport of 2-deoxy-d-glucose, a nonmetabolizable glucose analogue, into aspergillus nidulans against a concentration gradient does not appear to require phosphorylation, despite the high levels of sugar phosphates accumulated rapidly within the cell. two other deoxy analogues of d-glucose, 6-deoxy-d-glucose and 1,5-anhydro-d-glucitol (1-deoxy-d-glucose), although they lack the c-6 and the c-1 hydroxyl groups, respectively, and thus cannot be phosphorylated in those positions, still competi ...19695361211

autoregulation of the synthesis of nitrate reductase in aspergillus nidulans.in aspergillus nidulans, the syntheses of nitrate and nitrite reductases are induced by nitrate, and are repressed by ammonium. it is possible in wild-type strains to overcome partially the repressive effect of ammonium, by the addition of high concentrations of nitrate to the growth medium. mutations which lead to the production of abnormal nitrate reductase affect in addition the control of the synthesis of the nitrate-metabolizing enzymes, which in these strains are produced constitutively. t ...19695776531
methylammonium resistance in aspergillus nidulans.mutants of aspergillus nidulans resistant to methylammonium toxicity are simultaneously derepressed in the presence of ammonium for apparently all ammonium-repressible activities. enzyme assays directly demonstrate derepression of nitrate, nitrite, and hydroxylamine reductases, xanthine dehydrogenase, urate oxidase, and allantoinase, whereas in vivo tests show that ammonium and methylammonium repression or inhibition (or both) is relieved in these mutants in pathways of nitrate assimilation, pur ...19695788705

permeability properties of aspergillus nidulans protoplasts.the regeneration of mycelial forms from protoplasts of mutant and wild-type strains of aspergillus nidulans was followed microscopically under conditions with which the rate of regeneration depends upon a specific transport function. this method has shown that at least four uptake systems-one for divalent anions, two for purines, and one for sugars-remain functional after removal of the cell wall.19695802597
organization of enzymes in the common aromatic synthetic pathway: evidence for aggregation in fungi.centrifugation in sucrose density gradients of partially purified extracts from six species of fungi, i.e., rhizopus stolonifer, phycomyces nitens, absidia glauca (phycomycetes), aspergillus nidulans (ascomycetes), coprinus lagopus, and ustilago maydis (basidiomycetes), indicate that the five enzymes catalyzing steps two to six in the prechorismic acid part of the polyaromatic synthetic pathway sediment together. the sedimentation coefficients for these enzymes are very similar in the six specie ...19695802608
