Escherichia Coli Transformation. We constructed several recombinant Escherichia coli strains to transform phosphoenolpyruvate. We knocked-out the key genes ptsI and ptsG in PTS system by using Red homologous recombination in E. The goal of the experiment is to transform E. Coli cells which has little natural competence of foreign DNA without electroporation treatment and got transformants with simple and quick treatment by a plasmid or a transposon and transposase complex.

Plasmid is a circular DNA existing outside the main bacterial chromosomes which acts as a vector. There are two types of transformation natural and artificial transformation. However several recent reports have shown that E. A novel type of natural transformation involving cell-derived DNA and a putative promoting pheromone. The bacteria are transformed by a combination of calcium chloride and heat shock. Cells DH5 JM109 and HB101 prepared by SEM are extremely competent for transformation 13 10 9 cfuμg of pBR322 DNA and can be stored in liquid nitrogen for at least 40 days without loss of competence.
Cell-to-cell transformation in Escherichia coli.
Escherichia coli do not have nuclear envelope surrounding the bacterial chromosome and also contains plasmids which are required in the process of transformation Sinha Redfield 2012. This bacterium is not generally recognized as naturally transformable. The basic experiment leads to the formation of green fluorescent colonies of Escherichia coli and can be extended to illustrate the specificity of the interaction between sugars and the AraC protein the phenomenon of carbon catabolite repression the substrate specificity of the β-lactamase encoded by the plasmid and the role of host restrictionmodification systems in the transformation. Transformation could occur naturally in some bacteria such as Escherichia coli. Escherichia coli do not have nuclear envelope surrounding the bacterial chromosome and also contains plasmids which are required in the process of transformation Sinha Redfield 2012. Unlike electroporation transformation using these competent cells is affected minimally by salts in DNA preparation.
