Expression of Recombinant 3-Beta Hydroxysteroid Dehydrogenase Protein in E. coli

Advances and challenges in recombinant protein expression in Escherichia coli

Production of Recombinant Proline Dehydrogenase Enzyme from Pseudomonas fluorescens pf-5 in E. coli System

Proline dehydrogenase (ProDH; 1.5.99.8) belongs to superfamily of amino acid dehydrogenase, which plays a significant role in the metabolic pathway from proline to glutamate. The goal of this research was gene cloning and characterization of ProDH enzyme from Pseudomonas fluorescens pf-5 strain. The gene encoding ProDH was isolated by means of PCR amplification and cloned in an IPTG inducible T...

Co-expression of recombinant human nerve growth factor with trigger factor chaperone in E. coli

Nerve growth factor (NGF) is a neurotrophic factor that is functional in the survival, maintenance and differentiation of nervous system cells. This protein has three subunits, of which the beta subunit has the main activity. Its structure consists of a cysteine knot motif made up of beta strands linked by disulfide bonds. It can be used as a therapeutic agent in the treatment of many diseases....

Transformation and gene expression study of recombinant fish GnRH in E. coli BL21 in order to produce recombinant hormone

Gonadotropin releasing hormone (GnRH) is a neuropeptide known to regulate reproduction in vertebrates. Different analogues of synthetic GnRH are used to induce final sexual maturation in fish breeders. The purpose of this research was to evaluate the expression of recombinant GnRH (rGnRH) in Escherichia coli BL21 to produce recombinant hormone. In the present research, the sequence of DNA relat...

Over Expression of Biologically Active Interferon Beta Using Synthetic Gene in E. coli

In this study, our previously reported novel synthetic gene encoding 166 residues of interferon-? was used for an efficient expression of IFN-?. The synthetic gene was cloned into pET21a expression vector and transferred into E. coli. Recombinant protein was over-expressed in the E. coli. Identity of the recombinant protein was confirmed by western blot analysis. The recombinant protein was bio...

hpv16 e7-ct (gp96) fusion protein: molecular cloning, expression and purification of a recombinant 6xhis-tagged protein in e. coli

the development of a therapeutic vaccine against human papillomavirus (hpv) is important for the control of cervical cancer. e7 is the major transforming protein produced in cervical cancers, and therefore represents potential tumor-specific antigen that could be the target of immunotherapy for cervical cancer. among different vaccine strategies, protein-based vaccines are capable of generating...
