intracellular crystalline ergosterol in neurospora.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

characterization and expression of the neurospora crassa nmt-1 gene.the neurospora crassa homologue of the yeast no message in thiamine ( nmt-1) gene was characterized. the deduced 342-amino-acid gene product has more than 60% identity with other fungal homologues and 42% similarity to a putative bacterial permease. in addition to three introns disrupting the coding sequence, a differentially spliced intron in the 5' untranslated region was also detected. unlike other fungi, the n. crassa nmt-1 gene is repressed only 6- to 8-fold by exogenous thiamine concentrat ...200313680155
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
