(shionogi research laboratory, fukushimaku, osaka, japan). occurrence of nucleotides in culture fluids of microorganisms. iii. nucleotide excretion by brevibacterium liquefaciens sp. n. with special reference to uridine diphospho-n-acetylglucosamine compounds. j. bacteriol. 84:1-8. 1962.-among various nucleotides excreted in the culture broth of brevibacterium liquefaciens sp. n., four uridine nucleotides containing n-acetylglucosamine were isolated. these were found to be uridine ... | 1962 | 14481473 |
| conversion of extradiol aromatic ring-cleaving homoprotocatechuate 2,3-dioxygenase into an intradiol cleaving enzyme. | the intra- and extradiol subfamilies of catechol-adduct ring-cleaving dioxygenases each exhibit nearly absolute fidelity for the ring cleavage position. this is often attributed to the fact that the oxygen activation mechanism of intradiol dioxygenases utilizes fe3+ while that of the extradiol enzymes employs fe2+, but the subfamilies also differ in primary sequence, structural fold, iron ligands, and second sphere active site amino acid residues. here, we examine the effects of the second spher ... | 2003 | 14505375 |
| threonine production by dihydrodipicolinate synthase-defective mutants of brevibacterium flavum. | a novel type of threonine-producing strains, dihydrodipicolinate synthase (dps)-defective mutants of brevibacterium flavum, was isolated as alpha-amino-beta-hydroxyvaleric acid (ahv)-resistant producers. the third selection markers used were a strong lysine inhibition of threonine production and a lower production of lysine than that of threonine in those derived from strains with feedback-sensitive and-resistant aspartokinase (ak), respectively. the maximum threonine production by these dps-def ... | 1990 | 14545904 |
| catabolism of volatile sulfur compounds precursors by brevibacterium linens and geotrichum candidum, two microorganisms of the cheese ecosystem. | two brevibacterium linens strains and the cheese-ripening yeast geotrichum candidum were compared with regard to their ability to produce volatile sulfur compounds (vscs) from three different precursors namely l-methionine, 4-methylthio-2-oxobutyric acid (kmba) and 4-methylthio-2-hydroxybutyric acid (hmba). all microorganisms were able to convert these precursors to vscs. however, although all were able to produce vscs from l-methionine, only g. candidum accumulated kmba when cultivated on this ... | 2003 | 14580796 |
| a novel mannitol teichoic acid with side phosphate groups of brevibacterium sp. vkm ac-2118. | the cell wall of brevibacterium sp. vkm ac-2118 isolated from a frozen (mean annual temperature -12 degrees c) late pliocene layer, 1.8-3 myr, kolyma lowland, russia, contains mannitol teichoic acid with a previously unknown structure. this is 1,6-poly(mannitol phosphate) with the majority of the mannitol residues bearing side phosphate groups at o-4(3). the structure of the polymer was established by chemical methods, nmr spectroscopy, and maldi-tof mass spectrometry. | 2003 | 14622270 |
| diversity of l-leucine catabolism in various microorganisms involved in dairy fermentations, and identification of the rate-controlling step in the formation of the potent flavour component 3-methylbutanal. | various microorganisms, belonging to the genera lactococcus, lactobacillus, streptococcus, leuconostoc, bifidobacterium, propionibacterium, brevibacterium, corynebacterium and arthrobacter, used in dairy fermentations such as cheese making, were analysed for their potential to convert leucine into flavour components, most notably 3-methylbutanal. a large variation between and within species was observed for various enzyme activities involved in the conversion pathway, e.g. transaminases, alpha-h ... | 2004 | 14624315 |
| involvement of diviva in the morphology of the rod-shaped actinomycete brevibacterium lactofermentum. | in brevibacterium lactofermentum, as in many gram-positive bacteria, a diviva gene is located downstream from the dcw cluster of cell-division- and cell-wall-related genes. this gene (diviva(bl)) is mostly expressed during exponential growth, and the protein encoded, diviva(bl,) bears some sequence similarity to antigen 84 (ag84) from mycobacteria and was detected with monoclonal antibodies against ag84. disruption experiments using an internal fragment of the diviva(bl) gene or a disrupted divi ... | 2003 | 14663085 |
| a mannitol teichoic acid containing rhamnose and pyruvic acid acetal from the cell wall of brevibacterium permense vkm ac-2280. | the cell wall of brevibacterium permense vkm ac-2280 contains two teichoic acids. the major polymer represents a 1,6-poly(mannitol phosphate) substituted wirh either l-rhamnose (approximately 70%, unit a) or (s)-acetal of pyruvic acid (approximately 30%, unit b) with the overall chain length approximately 10 mannitol phosphate units. [carbohydrate structure: see text] the other polymer is an unsubstituted 1,3-poly(glycerol phosphate). the structures of the polymers were established using chemica ... | 2003 | 14670732 |
| performance of four sources of cholesterol oxidase for serum cholesterol determination by the enzymatic endpoint method. | cholesterol oxidase is used for the determination of serum cholesterol. it can be derived from streptomyces, pseudomonas fluorescens, cellulomonas, and brevibacterium. this study compared the performance characteristics of four enzymes in the endpoint cholesterol determination. | 2004 | 14687904 |
| mur-lh, the broad-spectrum endolysin of lactobacillus helveticus temperate bacteriophage phi-0303. | phi-0303 is a temperate bacteriophage isolated from lactobacillus helveticus cnrz 303 strain after mitomycin c induction. in this work, the gene coding for a lytic protein of this bacteriophage was cloned using a library of phi-0303 in escherichia coli dh5alpha. the lytic activity was detected by its expression, using whole cells of the sensitive strain l. helveticus cnrz 892 as the substrate. the lysin gene was within a 4.1-kb dna fragment of phi-0303 containing six open reading frames (orfs) a ... | 2004 | 14711630 |
| identification of a gene encoding lon protease from brevibacillus thermoruber wr-249 and biochemical characterization of its thermostable recombinant enzyme. | a gene encoding thermostable lon protease from brevibacillus thermoruber wr-249 was cloned and characterized. the br. thermoruber lon gene (bt-lon) encodes an 88 kda protein characterized by an n-terminal domain, a central atpase domain which includes an ssd (sensor- and substrate-discrimination) domain, and a c-terminal protease domain. the bt-lon is a heat-inducible gene and may be controlled under a putative bacillus subtilis sigmaa-dependent promoter, but in the absence of circe (controlling ... | 2004 | 14764100 |
| reclassification of brevibacterium liquefaciens okabayashi and masuo 1960 as arthrobacter nicotianae giovannozzi-sermanni 1959. | brevibacterium liquefaciens atcc 14929(t) was reclassified as corynebacterium liquefaciens by lanéelle et al. (1980). a further study by stackebrandt et al. (1983) described the same strain, indicating high genomic and chemotaxonomic relatedness to arthrobacter nicotianae; however, reclassification was not formally proposed. because of the discrepancies between their previous work and the data of collins & kroppenstedt (1983), lanéelle and colleagues re-examined b. liquefaciens and withdrew thei ... | 2004 | 15023984 |
