characterization of ribosomes from neurospora crassa.ribosomes isolated from growing hyphae of neurospora crassa contain 53 per cent protein and 47 per cent rna and have a sedimentation coefficient of 81s at 20 degrees c and infinite dilution. these ribosomes are stable at ph 7.4 in the presence of 0.01 m and 0.002 m mgcl(2) but undergo a dissociation into smaller particles if the mgcl(2) concentration is lowered to 0.0001 m. two types of rna with sedimentation coefficients of 19s(20) (50) and 13s(20) (50) have been extracted from the 81s particle ...196313984420

formation of mitochondria in neurospora crassa. a quantitative radioautographic study.cells of a choline-requiring mutant of neurospora crassa, labeled with radioactive choline, were transferred to unlabeled medium. at various times during their subsequent logarithmic growth, a highly purified mitochondrial fraction was prepared by sucrose density gradient centrifugation, and the distribution of label among individual mitochondria was determined by quantitative autoradiography. preliminary experiments indicated that, under the conditions of this "washout" experiment, choline serv ...196313931478
regulation of early reactions in the biosynthesis of tryptophan in neurospora crassa.lester, gabriel (reed college, portland, ore.). regulation of early reactions in the biosynthesis of tryptophan in neurospora crassa. j. bacteriol. 85:468-475. 1963.-the regulation of the biosynthesis of tryptophan was examined in neurospora crassa, strain ylo-tryp-la, which accumulates anthranil compounds. the block in this strain appeared to be in the conversion of 1-(o-carboxyphenylamino)-1-deoxyribulose-5-phosphate to indole-3-glycerol phosphate, since the dephosphorylated form of the former ...196313929917
intracellular crystalline ergosterol in the fungus neurospora crassa, hexagonal crystalline inclusions have been observed with both the light and electron microscopes. these crystals have been enriched by differential centrifugation and found to be identical with ergosterol by the criteria of ultraviolet spectral analysis and cytochemical analysis. observations have been made on the distribution and fine structure of the crystalline bodies in various wild type and mutant strains of n. crassa.196113922856
dehydrogenases of neurospora crassa.malate, isocitrate, glucose-6-phosphate, and 6-phosphogluconate dehydrogenases of the homogenate prepared from the mycelia of several wild strains of neurospora crassa have been subjected to zone electrophoresis in starch gel. four electrophoretically different malate dehydrogenases, a single isocitrate dehydrogenase, three glucose-6-phosphate dehydrogenases, and two 6-phosphogluconate dehydrogenases were obtained regardless of the strain or the media in which the organism was grown.196213922762

colonial growth of neurospora. sorbose and enzymes alter the composition of the cell wall and induce morphological changes.l-sorbose, an agent which induces colonial growth in neurospora crassa, also induces structural changes in the cell wall. acid hydrolyzates of cell walls isolated from sorbose-grown (colonial) hyphae contain more glucosamine and less glucose than do hydrolyzates of cell walls obtained from normally growing hyphae. snail digestive juice, an agent which effects a structural change in the cell wall of n. crassa by liberating from it large quantities of glucose, has been found to induce colonial gro ...196113884568

arginine and pyrimidine biogenesis in neurospora.the growth-promoting activity of propionic acid and related compounds for the pyrimidine-less strain, neurospora crassa 1298, is markedly inhibited by arginine. the data suggest that arginine exerts an inhibitory effect upon or represses the synthesis of an enzyme involved in pyrimidine formation.196113697950

tartaric acid metabolism of neurospora crassa.the growth of wild type neurospora crassa is stimulated by various organic acids including tartaric, tartronic, and mesoxalic acids. evidence is presented that this organism converts d- or l-tartaric acid to tartronic and mesoxalic acid, probably by fixation of co(2).195913675775
enzymatic activity of a genetically altered tryptophan synthetase in neurospora crassa.partially purified preparations of certain tryptophan-requiring mutants of neurospora crassa, which contain a protein (crm) antigenically related to wild-type tryptophan synthetase, possess indole glycerol phosphate-synthesizing activity. this activity can be inhibited by anti-crm sera. it is suggested that crm in such mutants represents a damaged tryptophan synthetase lacking the capacity to react with l-serine.195913668507
