Production of recombinant cholesterol oxidase containing covalently bound FAD in Escherichia coli

Production of recombinant cholesterol oxidase containing covalently bound FAD in Escherichia coli

BACKGROUND Cholesterol oxidase is an alcohol dehydrogenase/oxidase flavoprotein that catalyzes the dehydrogenation of C(3)-OH of cholesterol. It has two major biotechnological applications, i.e. in the determination of serum (and food) cholesterol levels and as biocatalyst providing valuable intermediates for industrial steroid drug production. Cholesterol oxidases of type I are those containin...

Production of recombinant proteins in Escherichia coli.

E. coli is the expression system of choice and a substantial body of literature has accumulated on the successful expression of foreign genes in this host. Several problems with protein expression in E. coli have been encountered, and many have been ultimately solved. This unit describes methods that have been developed for production of recombinant proteins in E. coli and potential pitfalls th...

Optimization of Cloning Conditions for high-level Production of Recombinant Mouse Interleukin-2 in Escherichia coli

Backgrounds and objectives: Interleukin 2 (IL-2) secreted by activated CD4+ T cells  has been known as a major mediator in both  adaptive and native immune system  due to a board range of effects on  different cells in the immunity system (1-6). Methods: cDNA synthesis was performed using gene- specific primers designed by Gene Runner software after RNA extraction of mouse splenocytes. PCR pro...

Polyhydroxyalkanoate production in recombinant Escherichia coli.

The bacterial species Escherichia coli has proven to be a powerful tool in the molecular analysis of polyhydroxyalkanoate (PHA) biosynthesis. In addition, E. coli holds promise as a source for economical PHA production. Using this microorganism, clones have been developed in our laboratory which direct the synthesis of poly-beta-hydroxybutyrate (PHB) to levels as high as 95% of the cell dry wei...
