The RIB element in the goaG-pspF intergenic region of Escherichia coli
(Amer Soc Microbiology, Washington, 1997)
The sequence (2,700 bp) between the aldH and pspF genes of Escherichia coli was determined, The pspF gene encodes a sigma(54) transcriptional activator of the phage shock protein (psp) operon (pspA to pspE), Downstream of ...
Analysis of exopolysaccharide production by Lactobacillus casei CG11, isolated from cheese
(Applied and Environmental Microbiology, 1992)
Exopolysaccharide-producing Lactobacillus casei CG11 was isolated from soft, white, homemade cheese. In basal minimal medium, it produces a neutral heteropolysaccharide consisting predominantly of glucose (about 75%) and ...
Constitutive interferon expression from retroviral vector
(Antiviral Research, 1993)
A genomic fragment with the human β-interferon gene was cloned into a pL3-4, a defective Moloney murine leukemia virus (M-MuLV) vector. Here we show that clones selected after viral infection of mouse NIH 3T3 cells ...
Nucleotide sequence analysis of the inversion termini located within IS3 elements α3β3 and β5α5 of Escherichia coli K-12
(Journal of Bacteriology, 1991)
This paper presents the first detailed structural analysis of termini of an inversion mediated by recombination between Escherichia coli native IS elements. The complete nucleotide sequence of the inversion termini in the ...
Nucleotide and amino acid polymorphism in the gene for L-histidinol dehydrogenase of Escherichia coli K12
(Oxford University Press, 1990)
Nucleotide sequence of the Escherichia coli K12 histidine operon revisited
(Academic Press, 1994)
We report on a significant difference between the published nucleotide sequence of the Escherichia coli K12 histidine operon and our sequencing results repeatedly obtained from a number of different E. coli K12 strains. ...
Characterization of a helicase, dhel III, from Drosophila melanogaster embryonic nuclei
(Taylor and Francis Inc., 1997)
Nuclear extracts prepared from Drosophila preblastoderm embryos contain a nucleoside 5'-triphosphate-dependent helicase that unwinds circular or linear partial duplex DNA substrates and moves along the DNA in 3' to 5' ...
Telomere-associated chromosome fragmentation: Applications in genome manipulation and analysis
(Nature Genetics, 1992)
Telomere-associated chromosome fragmentation (TACF) is a new approach for chromosome mapping based on the non-targeted introduction of cloned telomeres into mammalian cells. TACF has been used to generate a panel of somatic ...
Den 1, den 2 and den 3, ATP-inhibited deoxyribonucleases from Dropsophila embryonic nuclei
(Springer, Dordrecht, 1998)
Three Drosophila embryonic deoxyribonucleases, designated den1, den2 and den3, are identified in nuclear extracts separated by glycerol density gradient centrifugation. Den1, removes short products from the 5'-ends of ...
The E2 region of HPV 16 in relation to different types of cervical lesions
(Journal of Medical Virology, 1993)
The presence of the E2 region of HPV 16 was determined by the polymerase chain reaction in biopsy samples with different histopathological diagnoses. The absence of the E2 gene was observed in 17 of 30 cases examined. The ...
