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

subapical wall synthesis and wall thickening induced by cycloheximide in hyphae of aspergillus nidulans.hyphae of aspergillus nidulans continued to synthesize all the major polysaccharide components of the cell wall when cycloheximide was added to cultures. in the presence of cycloheximide, hyphae did not elongate, but electron microscopy showed that the walls became thicker around the cell. the conclusion that cycloheximide changed wall synthesis from extension at the apex to subapical thickening was supported by grain distributions on radioautograms of mutant hyphae labeled with galactose. these ...19734574700

isocitrate lyase from a thermophilic bacillus: effect of salts on enzyme activity.the isocitrate lyase from a thermophilic bacillus is activated about threefold by a variety of salts. such strong stimulation of activity is not seen with isocitrate lyase from the mesophiles, bacillus licheniformis, bacillus megaterium, escherichia coli, and aspergillus nidulans. the salt activation is markedly ph-dependent. at ph values above 8.6, salt (kcl) indeed inhibits the enzyme activity. potassium chloride also causes a significant shift of the ph optimum of the enzyme towards the acid ...19734584800

mutational analysis of dark endogenous metabolism in the blue-green bacterium anacystis nidulans.we describe a mutant (strain 704) of the obligate photoautotroph anacystis nidulans which behaves like the wild type under continuous illumination but which in the dark rapidly loses viability, respires little, and incorporates label into ribonucleic acid and protein at rates considerably less than observed with the darkened wild type. extracts of this mutant strain show no detectable 6-phosphogluconate dehydrogenase (ec activity. spontaneous revertants of mutant 704 were selected as s ...19744212183

autogenous regulation of gene expression.a new term, autogenous regulation, is used to describe a phenomenon that is not a new discovery but rather is newly appreciated as a mechanism common to a number of systems in both prokaryotic and eukaryotic organisms. in this mechanism the product of a structural gene regulates expression of the operon in which that structural gene resides. in many (perhaps all) cases, the regulatory gene product has several functions, since it may act not only as a regulatory protein but also as an enzyme, str ...19744589900

mutants of the pentose phosphate pathway in aspergillus nidulans.mutants of the pentose phosphate pathway have been isolated in aspergillus nidulans. these fail to grow on a variety of carbohydrates that are catabolized through the pentose phosphate pathway. they also grow poorly on nitrate and nitrite as sole nitrogen sources. the pentose phosphate pathway mutations have been assigned to two unlinked genes. mutants with lesions in the pppb locus have reduced activities of four enzymes of the pentose phosphate pathway, of glucose-phosphate isomerase, and of m ...19744591946
