Site-Directed Mutagenesis, Expression and Biological Activity of E. coli 5-Enolpyruvylshikimate 3-Phosphate Synthase Gene
Site-directed mutagenesis (SDM) as a powerful technique was used to change two important and conserved amino acids in 5-enolpyruvylshikimate 3- phosphate synthase (EPSPS) gene of E. coli. The mutations changed glycine 96 to alanine and alanine 183 to threonine. These two amino acids are very important for intraction of the wide spectrum herbicide, glyphosate, to EPSP synthase enzymes. By design...
متن کاملSite-Directed Mutagenesis Study
Structural elements of the rat 1.t-opioid receptor important in ligand receptor binding and selectivity were examined using a site-directed mutagenesis approach. Five single amino acid mutations were made, three that altered conserved residues in the ~ 8, and K receptors (Asn 15°t Ala, His297 to Ala, and Tyr326 to Phe) and wo de igned to test for ~i/8 selectivity (lie198 to Val and Va1202 to li...

متن کاملSite-directed, recombination-mediated mutagenesis of a complex gene locus.
We have generated a site-specific 17 bp insertion within a 38 kb chick globin gene cluster by employing the recombination abilities of Saccharomyces cerevisiae. This gene cluster contains four beta-type globin genes which share a high degree of sequence homology. In this procedure, a small fragment of beta A-globin DNA containing a 17 bp insertion is subcloned into a URA3-based yeast integratin...
متن کاملConstruction of a recombinant vector for site-directed mutagenesis in Salmonella typhimurium
BACKGROUND: Among all common techniques in sitedirectedmutagenesis, λ Red recombinase system has beenwidely used to knock out chromosomal genes in bacteria. In thismethod, there is always the risk of DNA Linear digestion byhost's restriction enzymes that leads to the low frequency ofrecombination. OBJECTIVES:To overcome this, we constructeda recombinant vector to disrupt phoP gene in Salmonella...
