| transformation of aspergillus oryzae using the a. niger pyrg gene. | a transformation system for aspergillus oryzae based on the orotidine-5'-phosphate decarboxylase gene (pyrg) was developed. transformation frequencies of up to 16 transformants per microgram of dna were obtained with the vector pab4-1, which carries the pyrg gene of a. niger. southern blotting analysis showed that vector dna sequences were integrated into the chromosomal dna, in various copy numbers and presumably at different sites. efficient cotransformation of an unselectable gene was also sh ... | 1987 | 3481025 |
| molybdenum cofactor: a compound in the in vitro activation of both nitrate reductase and trimethylamine-n-oxide reductase activities in escherichia coli k12. | nitrate reductase (nitrite: (acceptor) oxidoreductase, ec 1.7.99.4) and trimethylamine n-oxide reductase (nadh : trimethylamine-n-oxide oxidoreductase, ec 1.6.6.9) activities were reconstituted by incubation of the association factor fa (the putative product of the chlb gene) with the soluble extract of the chlb mutant grown anaerobically in the presence of trimethylamine n-oxide. when soluble extracts of the chlb mutant grown on 10 mm sodium tungstate, a molybdenum competitor, were used in comp ... | 1986 | 3524687 |
| activation in vitro of respiratory nitrate reductase of escherichia coli k12 grown in the presence of tungstate. involvement of molybdenum cofactor. | the chlorate-resistant (chlr) mutants are pleiotropically defective in molybdoenzyme activity. the inactive derivative of the molybdoenzyme, respiratory nitrate reductase, present in the cell-free extract of a chlb mutant, can be activated by the addition of protein fa, the probable active product of the chlb locus. protein fa addition, however, cannot bring about the activation if 10 mm sodium tungstate is included in the culture medium for the chlb strain. the inclusion of a heat-treated prepa ... | 1986 | 3525161 |
| further characterization of trimethylamine n-oxide reductase from escherichia coli, a molybdoprotein. | escherichia coli trimethylamine n-oxide (tmao) reductase i, the major enzyme among inducible tmao reductases, was purified to homogeneity by an improved method including heat treatment, ammonium sulfate precipitation, and chromatographies on bio-gel a-1.5m, deae-cellulose, and reactive blue-agarose. the molecular weight was estimated by gel filtration to be approximately 200,000. a single subunit peptide with a molecular weight of 95,000 was found by sodium dodecyl sulfate-polyacrylamide gel ele ... | 1986 | 3528139 |

| extraction and purification of molybdenum cofactor from milk xanthine oxidase. | molybdenum cofactor (mocofactor) is extracted efficiently, free of impurities and in high concentrations, by acid treatment of xanthine oxidase and subsequent incubation of the precipitate with phosphate buffer containing edta, molybdate and oxygen. it is suggested that cofactor is bound to the enzyme via hydrophobic forces as well as via an oxygen-sensitive mechanism. upon extraction, the capability to complement the apo nitrate reductase of neurospora crassa nit-1 can be conserved only in the ... | 1987 | 3691496 |
| molybdopterin cofactor from methanobacterium formicicum formate dehydrogenase. | the molybdopterin cofactor from the formate dehydrogenase of methanobacterium formicicum was studied. the cofactor was released by guanidine denaturation of homogeneous enzyme, which also released greater than 80% of the molybdenum present in the enzyme. the anoxically isolated cofactor was nonfluorescent, but after exposure to air it fluoresced with spectra similar to those of described molybdopterin cofactors. aerobic release from acid-denatured formate dehydrogenase in the presence of i2 and ... | 1986 | 3700335 |

| involvement of a particular species of beta-tubulin (beta 3) in conidial development in aspergillus nidulans. | strains of aspergillus containing the bena22 mutation are resistant to benomyl for vegetative growth but do not produce conidia. to test whether conidiation involved an additional benomyl-sensitive tubulin (i.e., was mediated by a tubulin other than the tubulins coded for by the bena locus), a collection of mutants was produced that formed conidia in the presence of benomyl, i.e., were conidiation-resistant (cr-) mutants. we analyzed the tubulins of these cr- mutants using two-dimensional gel el ... | 1985 | 3897246 |
| identification and functional analysis of beta-tubulin genes by site specific integrative transformation in aspergillus nidulans. | we have cloned two different beta-tubulin sequences from the filamentous fungus aspergillus nidulans. each was used in the construction of transforming plasmids that carry the pyr4 gene of neurospora crassa. we used these plasmids to transform a pyrg-strain of aspergillus to uridine prototrophy. both plasmids were shown to integrate site specifically into the homologous chromosomal sequences. we then used transformant strains in genetic crosses to demonstrate that one of the cloned beta-tubulin ... | 1985 | 3897247 |

| specific inhibition of mitochondrial protein synthesis influences the amount of complex i in mitochondria of rat liver and neurospora crassa directly. | specific inhibition of mitochondrial protein synthesis reduces the oxidation rate of nadh-linked substrates in rat liver as well as in neurospora crassa mitochondria. the present study shows that this is due to the fact that inhibition of mitochondrial protein synthesis leads to a decrease of the concentration of active complex i. therefore, these results demonstrate that at least one of the genes for the subunits of complex i is localized on mitochondrial dna. | 1985 | 3934002 |
| the mitochondrial genome of the fission yeast schizosaccharomyces pombe. the cytochrome b gene has an intron closely related to the first two introns in the saccharomyces cerevisiae cox1 gene. | the dna sequence of the cob region of the schizosaccharomyces pombe mitochondrial dna has been determined. the cytochrome b structural gene is interrupted by an intron of 2526 base-pairs, which has an open reading frame of 2421 base-pairs in phase with the upstream exon. the position of the intron differs from those found in the cob genes of saccharomyces cerevisiae, aspergillus nidulans or neurospora crassa. the sch. pombe cob intron has the potential of assuming an rna secondary structure almo ... | 1985 | 4046021 |

| uncoupling of the recbc atpase from dnase by dna crosslinked with psoralen. | exonucleolytic cleavage of dna by the recbc dnase is accompained by a dna-dependent atp hydrolysis that ceases when the dna that has been digested to a limit. on the other hand, dna that has been crosslinked by 4,5',8-trimethylpsoralen in the presence of 360-nm light remains an effective cofactor in the atpase reaction, but is resistant to digestion by the enzyme. psoralentreated dna is degraded by pancreatic dnase, micrococcal nuclease, and escherichia coli b restriction enzyme, but not by neur ... | 1972 | 4263506 |

| 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 |
