Whole-Genome Analysis of the Methyl tert -Butyl Ether-Degrading Beta-Proteobacterium Methylibium petroleiphilum PM1
Journal of Bacteriology - Tập 189 Số 5 - Trang 1931-1945 - 2007
Staci R. Kane, Anu Chakicherla, Patrick Chain, Radomir Schmidt, Maria Shin, Tina C. Legler, Kate M. Scow, Frank W. Larimer, Susan Lucas, Paul M. Richardson, Krassimira R. Hristova
ABSTRACT Methylibium petroleiphilum PM1 is a methylotroph distinguished by its ability to completely metabolize the fuel oxygenate methyl tert -butyl ether (MTBE). Strain PM1 also degrades aromatic (benzene, toluene, and xylene) and straight-chain (C ...... hiện toàn bộ
Comparative Genome Sequence Analysis of Multidrug-Resistant Acinetobacter baumannii
Journal of Bacteriology - Tập 190 Số 24 - Trang 8053-8064 - 2008
Mark D. Adams, Karrie Goglin, Neil Molyneaux, Kristine M. Hujer, Heather Lavender, Jennifer J. Jamison, Ian J. MacDonald, Kristienna M. Martin, Thomas A. Russo, Anthony A. Campagnari, Andrea M. Hujer, Robert A. Bonomo, Steven R. Gill
ABSTRACT The recent emergence of multidrug resistance (MDR) in Acinetobacter baumannii has raised concern in health care settings worldwide. In order to understand the repertoire of resistance determinants and their organization and origins, we compared the genome sequences of three MDR and t...... hiện toàn bộ
Protein-protein communication within the transcription apparatus

Cell Death in Pseudomonas aeruginosa Biofilm Development
Journal of Bacteriology - Tập 185 Số 15 - Trang 4585-4592 - 2003
Jeremy S. Webb, Lyndal S. Thompson, S. R. James, Tim Charlton, Tim Tolker‐Nielsen, Birgit Koch, Michael Givskov, Staffan Kjelleberg
ABSTRACT Bacteria growing in biofilms often develop multicellular, three-dimensional structures known as microcolonies. Complex differentiation within biofilms of Pseudomonas aeruginosa occurs, leading to the creation of voids inside microcolonies and to the dispersal of cells from within the...... hiện toàn bộ
Involvement of Nitric Oxide in Biofilm Dispersal of Pseudomonas aeruginosa
Journal of Bacteriology - Tập 188 Số 21 - Trang 7344-7353 - 2006
Nicolas Barraud, Daniel J. Hassett, Sung Hei Hwang, Stuart A. Rice, Staffan Kjelleberg, Jeremy S. Webb
ABSTRACT Bacterial biofilms at times undergo regulated and coordinated dispersal events where sessile biofilm cells convert to free-swimming, planktonic bacteria. In the opportunistic pathogen Pseudomonas aeruginosa , we previously observed that dispersal occurs concurrently with three interr...... hiện toàn bộ
Nitric Oxide Signaling inPseudomonas aeruginosaBiofilms Mediates Phosphodiesterase Activity, Decreased Cyclic Di-GMP Levels, and Enhanced Dispersal
Journal of Bacteriology - Tập 191 Số 23 - Trang 7333-7342 - 2009
Nicolas Barraud, David Schleheck, Janosch Klebensberger, Jeremy S. Webb, Daniel J. Hassett, Stuart A. Rice, Staffan Kjelleberg
ABSTRACTBacteria in biofilms often undergo active dispersal events and revert to a free-swimming, planktonic state to complete the biofilm life cycle. The signaling molecule nitric oxide (NO) was previously found to trigger biofilm dispersal in the opportunistic pathogenPseudomonas aeruginosaat low, nontoxic concentrations (N. Barraud, D....... hiện toàn bộ
Effects of Escherichia coli dnaE antimutator alleles in a proofreading-deficient mutD5 strain
Journal of Bacteriology - Tập 177 Số 20 - Trang 5979-5986 - 1995
Iwona J. Fijałkowska, Roel M. Schaaper
We have previously isolated seven mutants of Escherichia coli which replicate their DNA with increased fidelity. These mutants were isolated as suppressors of the elevated mutability of a mismatch-repair-defective mutL strain. Each mutant was shown to contain a single amino acid substitution in the dnaE gene product, the alpha (i.e., polymerase) subunit of DNA polymerase III holoenzyme res...... hiện toàn bộ
Influence of impaired chaperone or secretion function on SecB production in Escherichia coli
Journal of Bacteriology - Tập 178 Số 21 - Trang 6097-6104 - 1996
Jörg P. Müller
The efficient export of proteins through the cytoplasmic membrane of Escherichia coli requires chaperones to maintain protein precursors in a translocation-competent conformation. In addition to SecB, the major chaperone facilitating export of particular precursors, heat shock-induced chaperones DnaK-DnaJ and GroEL-GroES are also involved in this process. By use of secB'-lacZ gene fusions ...... hiện toàn bộ
Effects of signal sequence mutations on the kinetics of alkaline phosphatase export to the periplasm in Escherichia coli
Journal of Bacteriology - Tập 167 Số 1 - Trang 160-167 - 1986
S Michaelis, J.F. Hunt, Jean‐Pierre Jacquot
We isolated a collection of mutants defective in the export of alkaline phosphatase to the periplasm. Two classes of mutants were obtained: one class with lesions unlinked to the phoA gene and a second class harboring linked mutations. Among the former class, one mutant is cold sensitive for growth and may be defective in a component of the Escherichia coli secretory apparatus. Included in...... hiện toàn bộ
Specificity of SOS mutagenesis in native M13lacI phage
Journal of Bacteriology - Tập 173 Số 24 - Trang 7996-7999 - 1991
Fumio Yatagai, Michael Horsfall, Barry W. Glickman
Base substitutions account for 90% of all forward mutations sequenced in unmodified M13lacI DNA grown in both UV-irradiated and nonirradiated hosts. The principal effect of SOS induction was an increase in the contribution of transversions, in particular A.T----T.A events.
