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
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
CIRCULIN AN ANTIBIOTIC FROM AN ORGANISM RESEMBLING BACILLUS CIRCULANS
Journal of Bacteriology - Tập 57 Số 3 - Trang 305-312 - 1949

Isolation and biochemical characterization of a novel lantibiotic mutacin from Streptococcus mutans
Journal of Bacteriology - Tập 176 Số 14 - Trang 4316-4320 - 1994
Jan Novák, Page W. Caufield, Edward J. Miller
Certain members of the indigenous biota of humans produce antimicrobial substances called bacteriocins, which inhibit other bacteria, including members of their own species. One of these substances, mutacin, is made by Streptococcus mutans, a member of the oral biota. Mutacin inhibits other mutans streptococci as well as many gram-positive exogenous pathogens. Here, we report for the first...... hiện toàn bộ
NADPH-dependent reductive ortho dehalogenation of 2,4-dichlorobenzoic acid in Corynebacterium sepedonicum KZ-4 and Coryneform bacterium strainNTB-1 via 2,4-dichlorobenzoyl coenzyme A
Journal of Bacteriology - Tập 178 Số 9 - Trang 2656-2661 - 1996
V. Romanov, Robert P. Hausinger
Corynebacterium sepedonicum KZ-4, described earlier as a strain capable of growth on 2,4-dichlorobenzoate (G.M. Zaitsev and Y.N. Karasevich, Mikrobiologiya 54:356-369, 1985), is known to metabolize this substrate via 4-hydroxybenzoate and protocatechuate, and evidence consistent with an initial reductive dechlorination step to form 4-chlorobenzoate was found in another coryneform bacterium...... hiện toàn bộ
Mutations at Residues 282, 286, and 293 of Phage λ Integrase Exert Pathway-Specific Effects on Synapsis and Catalysis in Recombination
Journal of Bacteriology - Tập 185 Số 8 - Trang 2653-2666 - 2003
Troy Bankhead, Bernard J. Etzel, Felise Wolven, Sylvain Bordenave, Jeffrey L. Boldt, Teresa A. Larsen, Anca M. Segall
ABSTRACTBacteriophage λ integrase (Int) catalyzes site-specific recombination between pairs of attachment (att) sites. Theattsites contain weak Int-binding sites called core-type sites that are separated by a 7-bp overlap region, where cleavage and strand exchange occur. We have characterized a number of mutant ...... hiện toàn bộ
Shedding light on anaerobic benzene ring degradation: a process unique to prokaryotes?

Isolation and characterization of a cyanide dihydratase from Bacillus pumilus C1
Journal of Bacteriology - Tập 175 Số 19 - Trang 6105-6112 - 1993
Paul R. Meyers, Douglas E. Rawlings, David Woods, G.G. Lindsey
A cyanide-degrading enzyme from Bacillus pumilus C1 has been purified and characterized. This enzyme consisted of three polypeptides of 45.6, 44.6, and 41.2 kDa; the molecular mass by gel filtration was 417 kDa. Electron microscopy revealed a multimeric, rod-shaped protein approximately 9 by 50 nm. Cyanide was rapidly degraded to formate and ammonia. Enzyme activity was optimal at 37 degre...... hiện toàn bộ
