Cloning of alginate lyase gene (alxM) and expression in Escherichia coli.
The alxM gene encoding a D-mannuronan-specific alginate lyase has been cloned from a marine bacterium isolated as an epiphyte on the brown alga, Sargassum fluitans. Expression of this gene in Escherichia coli provides a source of this enzyme for probing alginate structure and modifying the mannuronan-rich alginate polymers produced by bacterial pathogens.
متن کاملCharacterization of the Pseudomonas aeruginosa alginate lyase gene (algL): cloning, sequencing, and expression in Escherichia coli.
Mucoid strains of Pseudomonas aeruginosa produce a viscous exopolysaccharide called alginate and also express alginate lyase activity which can degrade this polymer. By transposon mutagenesis and gene replacement techniques, the algL gene encoding a P. aeruginosa alginate lyase enzyme was found to reside between algG and algA within the alginate biosynthetic gene cluster at 35 min on the P. aer...
متن کاملCloning and Expression of Mannheimia haemolytica PlpE Gene in Escherichia coli and its Immunogenicity Assessment
Mannheimia haemolytica is responsible for considerable economic losses to cattle, sheep, and goat industries in many parts of the world. This bacterium isone of the causative agents of shipping fever in cattle. Current vaccines against M. haemolytica are moderately efficacious since they do not provide complete protection against the disease. Production of a...
متن کاملCloning and expression of Eimeria necatrix microneme5 gene in Escherichia coli
Background: Coccidiosis caused by Eimeria necatrix has the most economic impact onpoultry production. Micronemal proteins in Eimeria necatrix are thoughtto be critical ligands determining host cell specificity at the time ofinvasion. OBJECTIVES: Isolation and purification of Eimeria necatrix oocysts from Khuzestan province of Iran was performed. AcDNA encoding microneme 5 (EnMIC5...
متن کاملCloning and optimization of phytase enzyme gene expression in Escherichia coli
Introduction Phytase is an enzyme that has the ability to break down phytic acid into myoinositol and mineral phosphate, and widely uses as an additive in animal foods. The aim of this study was to achieve a high level of bacterial phytase expression in PET26b expression host. Materials and Methods To generate the recombinant phytase enzyme, the target gene was introduced into the expression ...
