Human vaginal Lactobacillus rhamnosus harbor mutation in 23S rRNA associated with erythromycin resistance
(Elsevier, Amsterdam, 2009)
Little is known about the diversity and distribution of resistance determinants in human commensal bacteria. The aim of this study was to determine the molecular mechanism responsible for high-level erythromycin resistance ...
Dinamika korišćenja natrijum dodecil sulfata i osetljivost na antibiotike soja Pseudomonas sp. ATCC19151 / Dynamics of sodium dodecyl sulfate utilization andantibiotic susceptibility of strain Pseudomonas sp. ATCC19151
(Srpsko biološko društvo, Beograd, i dr., 2009)
Poznato je da soj Pseudomonas sp. ATCC19151 poseduje gen koji kodira Potencijalnu alkilsulfatazu. U ovom radu analizirana je sposobnost rasta ovog soja u minimalnom medijum usa različitim koncentracijama natrijum dodecilsulfata ...
5 ' untranslated region of the Pseudomonas putida WCS358 stationary phase sigma factor rpoS mRNA is involved in RpoS translational regulation
(Microbiology Soc Korea, Seoul, 2008)
The sigma(S) subunit of RNA polymerase is a central regulator which governs the expression of a host of stationary phase-induced and osmotically regulated genes in Gram-negative bacteria. The Pseudomonas putida rpoS gene ...

A novel hypothesis regarding the possible involvement of cytosolic phospholipase 2 in insulin-stimulated proliferation of vascular smooth muscle cells
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
Insulin (INS) via INS receptor acts as a mitogen in vascular smooth muscle cells (VSMCs) through stimulation of multiple signaling mechanisms, including p42/44 mitogen-activated protein kinase (ERK1/2) and phosphatidyl ...
Novel mechanism of bacteriocin secretion and immunity carried out by lactococcal multidrug resistance proteins
(Amer Soc Biochemistry Molecular Biology Inc, Bethesda, 2003)
A natural isolate of Lactococcus lactis was shown to produce two narrow spectrum class II bacteriocins, designated LsbA and LsbB. The cognate genes are located on a 5.6-kb plasmid within a gene cluster specifying LmrB, an ...
Identification of quorum-sensing-regulated genes of Burkholderia cepacia
(Amer Soc Microbiology, Washington, 2003)
Quorum sensing is a regulatory mechanism (operating in response to cell density) which in gram-negative bacteria usually involves the production of N-acyl homoserine lactones (HSL). Quorum sensing in Burkholderia cepacia ...
Role of GacA, LasI, RhlI, ppk, PsrA, vfr and ClpXP in the regulation of the stationary-phase sigma factor rpoS/RpoS in Pseudomonas
(Springer-Verlag, New York, 2003)
RpoS is the stationary phase sigma factor responsible for increased transcription of a set of genes when bacterial cells enter stationary phase and under stress conditions. In Escherichia coli, RpoS expression is modulated ...
Characterization of cell envelope-associated proteinases of thermophilic lactobacilli
(Wiley, 2001)
The proteolytic activities of two natural isolates of thermophilic lactobacilli, Lactobacillus acidophilus BGRA43 and Lact, delbrueckii BGPF1, and Lact. acidophilus CH2 (Chr. Hansen's strain) and Lact, acidophilus V74 ...
Regulation of rpoS gene expression in Pseudomonas: involvement of a TetR family regulator
(Amer Soc Microbiology, Washington, 2001)
The rpoS gene encodes the sigma factor which was identified in several gram-negative bacteria as a central regulator during stationary phase. rpoS gene regulation is known to respond to cell density, showing higher expression ...
