IlvHI locus of Salmonella typhimurium [PDF]

Journal of Bacteriology, 1983
In Escherichia coli K-12, the ilvHI locus codes for one of two acetohydroxy acid synthase isoenzymes. A region of the Salmonella typhimurium genome adjacent to the leucine operon was cloned on plasmid pBR322, yielding plasmids pCV47 and pCV49 (a shortened version of pCV47). This region contains DNA homologous to the E.

Amazonian Cyanobacteria as a Source of Bioactive Compounds With Antimicrobial and Cytotoxic Properties

Chemistry &Biodiversity, EarlyView.
ABSTRACT Cyanobacteria are photosynthetic microorganisms known for producing diverse bioactive compounds. This study explores the bioactivity of extracts and fractions from Amazonian cyanobacteria and their pigment and phenolic compound production. A fraction from Synechococcus sp. CACIAM 05 showed cytotoxicity against hCMEC/D3 and MG‐63 cells.

Composition, Chemical Variability, and Anti‐inflammatory Activity of the Berry Essential Oil of Juniperus phoenicea L. var. Turbinata From Algeria

Chemistry &Biodiversity, EarlyView.
ABSTRACT The chemical composition of 66 oil samples isolated from the berries of individual trees of Juniperus phoenicea var. turbinata, collected in six locations from Algeria, was investigated by gas chromatography with flame ionization detection, gas chromatography‐mass spectrometry, and 13C‐nuclear magnetic resonance.

Salmonella typhimurium Suppresses Tumor Growth via the Pro-Inflammatory Cytokine Interleukin-1β

Theranostics, 2015
Although strains of attenuated Salmonella typhimurium and wild-type Escherichia coli show similar tumor-targeting capacities, only S. typhimurium significantly suppresses tumor growth in mice. The aim of the present study was to examine bacteria-mediated

Type III Secretion Effectors with Arginine N-Glycosyltransferase Activity [PDF]

, 2020
Type III secretion systems are used by many Gram-negative bacterial pathogens to inject proteins, known as effectors, into the cytosol of host cells. These virulence factors interfere with a diverse array of host signal transduction pathways and cellular
