| in vitro formation of an active multienzyme complex in the tryptophan pathway of neurospora crassa. | a multienzyme complex that catalyzes the anthranilate synthetase, phosphoribosylanthranilate (pra) isomerase, and indoleglycerolphosphate (ingp) synthetase reactions was produced in vitro when extracts from a tryp-1 mutant and a tryp-2 mutant of neurospora crassa were mixed. the sedimentation values and the molecular weights for the interacting components obtained from the mutants were estimated by sucrose gradients and by gel filtration on sephadex columns. the component coded for by the tryp-2 ... | 1969 | 5264137 |

| mutants affecting thymidine metabolism in neurospora crassa. | when (14)c-thymidine labeled only in the ring is administered to neurospora crassa, the majority of the recovered label is found in the ribonucleic acid (rna). three mutants were isolated in which different steps are blocked in the pathway that converts the pyrimidine ring of thymidine to an rna precursor. evidence from genetic, nutritional, and accumulation studies with the three mutants shows the pathway to proceed as follows: thymidine --> thymine --> 5-hydroxymethyluracil --> 5-formyluracil ... | 1969 | 5344102 |

| genetic determinants of circadian rhythmicity in neurospora. | timex, a strain of neurospora crassa which exhibits a circadian rhythm of conidia formation in growth-tube cultures, has been found to differ from wild-type strains by two genes. one gene, inv, is responsible for an invertase deficiency, whereas the second gene, bd, is of unknown function. both genes map independently from other genes known to induce neurospora rhythmicity. the inv gene is not essential for the timex phenotype because bd strains express that phenotype on certain media. although ... | 1969 | 5773032 |

| neurospora mutant exhibiting hyperproduction of amylase and invertase. | a mutant strain of neurospora crassa has been isolated which is derepressed for amylase and beta-fructofuranosidase (invertase). large amounts of the two enzymes were secreted into the culture medium upon depletion of exogenous carbon source. the resulting increases of the two extracellular enzymes were prevented by actinomycin d, cycloheximide, and glycerol. the starving cells of the mutant strain produced amylase and invertase de novo, as evidenced by incorporation of radioactive amino acids i ... | 1969 | 5773010 |

| pyrimidine synthesis in neurospora crassa: regulation of enzyme activities. | the regulation of several enzymes involved in pyrimidine biosynthesis in neurospora crassa has been studied. elevation of atcase (l-aspartate carbamoyltransferase) activity is found in all pyrimidine-requiring mutants when they are starved for uridine. dhoase (dihydroorotase) is an unstable enzyme, and it is impossible to conclude what type of regulation, if any, controls this enzyme. dhodehase (dihydroorotate dehydrogenase) activity shows a marked elevation in uridine-starved pyr-2 cultures, a ... | 1969 | 5361219 |

| the facile isolation of a structural phospholipoprotein from hydrogenomon as facilis and neurospora crassa. | the paper describes a new and gentle procedure for isolating "structural" phospholipoproteins from organisms and the first such isolation from a procaryotic microbe, hydrogenomonas facilis. the amino acid composition of its protein moiety resembles that of "structural protein" from other sources. although disc gel electrophoresis has shown the protein to be heterogeneous, this is attributed to aggregation. | 1969 | 4978742 |

| multiple phenylalanyl-transfer ribonucleic acid synthetase activities in the cytoplasm of neurospora crassa. | several trna's specific for a particular amino acid have been shown to exist in multiple, or isoaccepting, forms. there is considerable interest in establishing whether multiple aminoacyl-trna synthetases also exist. we present evidence that the cytoplasm of neurospora crassa contains three chromatographically separable phenylalanyl-trna synthetases distinct from mitochondrial phenylalanyl-trna synthetase. in addition to differences in chromatographic properties the three enzymes exhibit differe ... | 1969 | 5256412 |

| codon recognition by enzymatically mischarged valine transfer ribonucleic acid. | direct evidence for the adaptor hypothesis has been obtained by examining the codon recognition of a purified escherichia coli valine transfer ribonucleic acid which was enzymatically mischarged with phenylalanine labeled with carbn-14 by reaction with purified phenylalanyl-transfer ribonucleic acid synthetase from neurospora crassa. the mischarged transfer ribonucleic acid recognized the valine codons but failed to recognize the phenylalanine codon when tested in trinucleotide-directed ribosoma ... | 1969 | 4902680 |

| gene-enzyme relationships in neurospora invertase. | a spontaneous, single-gene mutation responsible for a total lack of invertase activity in neurospora crassa is described. the mutation is believed to lie in the structural gene for invertase, since an immunologically cross-reacting protein is made by the mutant strain. in addition, there was no evidence for a defect in regulation of invertase activity or synthesis by the following criteria. (i) the invertaseless condition was recessive in heterokaryons; (ii) no invertase inhibitor was found in m ... | 1969 | 4975154 |
