Chromosome mosaicism in prenatal diagnosis (cytogenetic and molecular studies)
(Karger, Basel, 1997)
Introducing fish into prenatal diagnosis
(Karger, Basel, 1997)
Filamentous phage infection-mediated gene expression: construction and propagation of the gIII deletion mutant helper phage R408d3
(Elsevier Science Bv, Amsterdam, 1997)
We describe the use of transcriptional fusions to the phage shock protein (psp) promoter. These fusions are expressed only when cells are infected by filamentous phage. In an application, the psp promoter was fused to the ...
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 ...
Role of upstream activation sequences and integration host factor in transcriptional activation by the constitutively active prokaryotic enhancer-binding protein PspF
(Academic Press Ltd, London, 1997)
PspF, the transcriptional activator of the pspA operon of Escherichia coli, which belongs to the enhancer binding protein (EBP) family of sigma(54) activator proteins, is constitutively active in an in vitro transcription ...
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' ...
Agrobacterium rhizogenes-mediated transformation and plant regeneration of four Gentiana species
(Springer, Dordrecht, 1997)
Shoots of micropropagated Gentiana acaulis, G. cruciata, G. lutea, and G. purpurea were inoculated with suspensions of Agrobacterium rhizogenes cells, strains ATCC 15834 or A4M70GUS. Adventitious roots appeared at the sites ...
PspF and IHF bind co-operatively in the psp promoter-regulatory region of Escherichia coli
(Wiley-Blackwell, Hoboken, 1997)
PspF bound to the psp enhancer activates E sigma(54) holoenzyme-dependent transcription of the Escherichia coli phage-shock protein (psp) operon and autogenously represses its own sigma(70)-dependent transcription, thereby ...
The Escherichia coli phage-shock-protein (psp) operon
(Blackwell Science Ltd, Oxford, 1997)
The phage-shock-protein (psp) operon helps to ensure survival of Escherichia coli in tate stationary phase at alkaline pH, and protects the cell against dissipation of its proton-motive force against challenge. It is ...
Autogenous control of PspF, a constitutively active enhancer-binding protein of Escherichia coli
(Amer Soc Microbiology, Washington, 1997)
Escherichia coli sigma(54)-dependent phage shock protein operon (pspA to -E) transcription is under the control of PspF, a constitutively active activator, sigma(70)-dependent transcription of pspF is under autogenous ...
