effect of l-sorbose on polysaccharide synthetases of neurospora crassa (glycogen- -1,3-glucan-morphology-cell wall-digitonin-particulate enzymes). | neurospora glycogen synthetase (ec 2.4.1.11) occurs in 100,000 x g particles. the two forms (glucose-6-phosphate dependent-independent) of glycogen synthetase were solubilized and separated by digitonin treatment of the 100,000 x g particles. glucan synthetase activity of neurospora was found only in a cell-wall preparation. these two enzymes have been characterized in relation to the paramorphogenic action of sorbose. sorbose-grown cultures showed a marked decrease in the specific activity of b ... | 1972 | 4258315 |
disruption of an amino acid transport mutant of neurospora crassa by kcl. | a double amino acid transport-deficient mutant (pm (-)nb) of neurospora crassa is shown to be altered in the molecular structure of its cell wall or membrane. this alteration was revealed by a high degree of cellular disruption and cell-cell interaction following extraction by a high molar concentration of kcl. | 1972 | 4258064 |

nh 2 -terminal residues of neurospora crassa proteins. | the nh(2)-terminal amino acid composition of the soluble and ribosomal proteins from neurospora crassa mycelia and conidia was determined by the dinitrophenyl method. a nonrandom distribution of nh(2)-terminal amino acids was observed in the complex protein mixtures. glycine, alanine, and serine accounted for 75% of the nh(2)-terminal amino acids, and glycine appeared most frequently in mature proteins of mycelia. the appearance of phenylalanine as one of the major nh(2)-termini in crude conidia ... | 1971 | 5095291 |
mitochondrial biogenesis in neurospora crassa. i. an ultrastructural and biochemical investigation of the effects of anaerobiosis and chloramphenicol inhibition. | the isolation of a new class of mutants permitting facultative anaerobiosis in neurospora crassa is described. backcross analyses to the obligate aerobe prototroph (an(-)) indicate single nuclear gene inheritance (an(-)/an(+)). an(+) and an(-) are indistinguishable in morphology and growth rates under aerobic conditions. anaerobic growth requires nutritional supplements that are dispensable for aerobic growth. conidiogenesis, conidial germination, and vegetative growth rate are suppressed by ana ... | 1971 | 4329155 |

regulation of tryptophan biosynthetic enzymes in neurospora crassa. | the formation of enzymatic activities involved in the biosynthesis of tryptophan in neurospora crassa was examined under various conditions in several strains. with growth-limiting tryptophan, the formation of four enzymatic activities, anthranilic acid synthetase (aas), anthranilate-5-phosphoribosylpyrophosphate phosphoribosyl transferase (prat), indoleglycerol phosphate synthetase (ingps), and tryptophan synthetase (ts) did not occur coordinately. aas and ts activities began to increase immedi ... | 1971 | 5563869 |
properties of an extracellular -galactosidase secreted by neurospora crassa. | an extracellular beta-galactosidase with an activity optimum at about ph 4 was found to occur in the filtrates of neurospora crassa strain 74a when this mold was grown on certain sugars. this activity accounted for a substantial portion of the beta-galactosidase activity in the culture. the beta-galactosidase in the medium appeared to be a secreted, extracellular enzyme, not a product of cell lysis. the extracellular activity was found to have physical and kinetic properties similar to those of ... | 1971 | 5563865 |
constitutive mutants in a regulatory gene exerting positive control of quinic acid catabolism in neurospora crassa. | in neurospora crassa, evidence has recently been obtained for a cluster of four closely-linked genes controlling the inducible enzymes catalyzing the first three reactions in the catabolism of quinic acid. three of these genes appear to be the structural genes for the three enzymes. the fourth gene, designated qa-1, has been interpreted as having a regulatory function, since qa-1 mutants are pleiotropic types, are noninducible for the three enzymes, and form heterocaryons which complement mutant ... | 1971 | 5283945 |

regulation of sugar transport in neurospora crassa. | sugar uptake systems in neurospora crassa are catabolically repressed by glucose. synthesis of a low k(m) glucose uptake system (system ii) in neurospora is derepressed during starvation for an externally supplied source of carbon and energy. fasting also results in the derepression of uptake systems for fructose, galactose, and lactose. in contrast to the repression observed when cells were grown on glucose, sucrose, or fructose, system ii was not repressed by growth on tryptone and casein hydr ... | 1971 | 5573733 |
kinetic characteristics of the two glucose transport systems in neurospora crassa. | glucose is transported across the cell membrane of neurospora crassa by two physiologically and kinetically distinct transport systems. system ii is repressed by growth of the cells in 0.1 m glucose. system i is synthesized constitutively. the apparent k(m) for glucose uptake by system i and system ii are 25 and 0.04 mm, respectively. both uptake systems are temperature dependent, and are inhibited by nan(3) and 2,4-dinitrophenol. glucose uptake by system ii was not inhibited by fructose, galact ... | 1971 | 5573732 |

metabolic role, regulation of synthesis, cellular localization, and genetic control of the glyoxylate cycle enzymes in neurospora crassa. | the glyoxylate shunt enzymes, isocitrate lyase and malate synthase, were present at high levels in mycelium grown on acetate as sole source of carbon, compared with mycelium grown on sucrose medium. the glyoxylate shunt activities were also elevated in mycelium grown on glutamate or casamino acids as sole source of carbon, and in amino acid-requiring auxotrophic mutants grown in sucrose medium containing limiting amounts of their required amino acid. under conditions of enhanced catabolite repre ... | 1971 | 5541006 |
neurospora mutant deficient in tryptophanyl-transfer ribonucleic acid synthetase activity. | a tryptophan auxotroph of neurospora crassa, trp-5, has been characterized as a mutant with a deficient tryptophanyl-transfer ribonucleic acid (trna) synthetase (ec 6.1.1.2) activity. when assayed by tryptophanyl-trna formation, extracts of the mutant have less than 5% of the wild-type specific activity. the adenosine triphosphate-pyrophosphate exchange activity is at about half the normal level. in the mutant derepressed levels of anthranilate synthetase and tryptophan synthetase were associate ... | 1971 | 5540999 |
partial enzyme aggregates formed by pleiotropic mutants in the arom gene cluster of neurospora crassa. | molecular weights of enzymically active arom aggregates produced by pleiotropic and various arom-1 mutants of neurospora crassa have been estimated by sucrose density gradient centrifugation. in contrast to most single-gene mutants (which produce intact arom multienzyme aggregates of normal molecular weight- about 230,000), pleiotropic mutants that lack two or more of the five enzyme activities in the arom aggregate produce partial arom aggregates of molecular weights ranging from about 60,000 t ... | 1971 | 5276302 |

synchronization of converging metabolic pathways: activation of the cystathionine gamma-synthase of neurospora crassa by methyltetrahydrofolate. | methyltetrahydrofolate synchronizes the activities of the two branches of the pathway of methionine biosynthesis in neurospora crassa by serving as an essential activator of cystathionine gamma-synthase and antagonizing the feedback inhibition of this enzyme by s-adenosylmethionine. activation is specific for the methylated form of folate and increases with increasing glutamate content. the inability of extracts of me-1 and me-6 mutants to form cystathionine that has been previously reported is ... | 1971 | 5277076 |
defective production of mitochondrial ribosomes in the poky mutant of neurospora crassa. | a strain of neurospora crassa containing a cytoplasmic mutation (poky) affecting mitochondrial function is shown to be deficient in small ribosomal subunits in the mitochondrion during the exponential growth phase. in the stationary growth phase, small subunits are more abundant and are present in mitochondrial ribosomal monomers. this change can be correlated with the return of mitochondrial cytochrome content to amounts approaching those of wild type mitochondria. the ribosomal defect shows an ... | 1971 | 5277071 |
