Saturation site-directed mutagenesis of thymidylate synthase.

We have subjected 12 different codons of a synthetic Lactobacillus casei thymidylate synthase (TS) gene to saturation site-directed mutagenesis to create amino acid "replacement sets" at each of those positions. The target residues were chosen because they are highly conserved and because they are important for the structure and function of the protein as indicated by solution and structural st...

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...

Patch cloning method for multiple site-directed and saturation mutagenesis

BACKGROUND Various DNA manipulation methods have been developed to prepare mutant genes for protein engineering. However, development of more efficient and convenient method is still demanded. Homologous DNA assembly methods, which do not depend on restriction enzymes, have been used as convenient tools for cloning and have been applied to site-directed mutagenesis recently. This study describe...

Site-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...
