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

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

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

photooxidative death in blue-green algae.when incubated in the light under 100% oxygen, wild-type blue-green algae (anacystis nidulans, synechococcus cedrorum) die out rapidly at temperatures of 4 to 15 c, and at 35 c (or at 26 c in the case of s. cedrorum) in the absence of co(2). photosynthesis is impaired in these cells long before they die. blocking of photosystem ii at high temperatures in the presence of co(2) sensitizes the algae to photooxidative death. photooxidative death and bleaching of photosynthetic pigments are separable ...19724626540

use of the immunodiffusion test in the serodiagnosis of aspergillosis.the diagnostic value of an immunodiffusion (id) test with standardized precipitinogens derived from five aspergillus species was determined with sera from 60 proven and 12 suspected cases of aspergillosis. the data demonstrated that the greatest number of aspergillosis cases were detected by the concurrent use of a. fumigatus and a. niger precipitinogens. with these precipitinogens, the id test permitted the serodiagnosis of aspergillosis in 82% of the 60 proven cases and in 83% of the 12 suspec ...19724622826

effects of ammonium, l-glutamate, and l-glutamine on nitrogen catabolism in aspergillus nidulans.during growth of aspergillus nidulans in medium containing ammonium the specific activities of most enzymes involved in catabolism of nitrogen sources are low (ammonium repression). the gdha10 lesion, which results in loss of nicotinamide adenine dinucleotide phosphate-linked glutamate dehydrogenase activity, has been shown to lead to partial relief of ammonium repression of three amidase enzymes as well as histidase. the area102 lesion led to altered levels of these enzymes but did not greatly ...19744612004
