mar Operon involved in multidrug resistance of Enterobacter aerogenes.
We determined the sequence of the entire marRAB operon in Enterobacter aerogenes. It is functionally and structurally analogous to the Escherichia coli operon. The overexpression of E. aerogenes MarA induces a multidrug resistance phenotype in a susceptible strain, demonstrated by a noticeable resistance to various antibiotics, a decrease in immunodetected porins, and active efflux of norfloxacin.

متن کاملA melibiose transporter and an operon containing its gene in Enterobacter cloacae.
We detected inducible melibiose transport activity in cells of Enterobacter cloacae IID977. H+, but not Na+, was found to be the coupling cation for this transporter. We cloned and sequenced the gene encoding the melibiose transporter. A homology search of a protein sequence database revealed that this melibiose transporter has high sequence similarity with the lactose transporter (LacY) and th...
متن کاملChromosomal beta-lactamase expression and antibiotic resistance in Enterobacter cloacae.
The activities of beta-lactam antibiotics were compared against Enterobacter cloacae clinical isolates and mutants which had inducible, stably-derepressed, and basal expression of a pI 8.4 subtype of the Ia chromosomal beta-lactamase. These activities were correlated with the results of studies of the beta-lactamase-lability and beta-lactamase-inducer-power of the antibiotics. Cefoxitin and amp...
متن کاملEvaluating the Production Yield of an Exopolysaccharide Produced by Enterobacter cloacae subsp. Dissolvens in Seawater
The aim of this study was to investigate the influence of different parameters on exopolysaccharide (EPS) production from Enterobacter cloacae subsp. dissolvens using seawater as a basal medium. For this purpose, the effect of carbon (sucrose, molasses, paraffin and sunflower oil) and nitrogen sources, NaCl concentration, incubation time, pH as well as seawater dilution or enrichment with disti...
