چکیده

Applying in silico simulations and in vitro experiments, the amino acid proline was proved to have a profound influence on Streptomyces griseus trypsinogen, and the hydrogen bond between H(57) and D(102) was found to be crucial for trypsin activity. By introducing an artificial propeptide, IVEF, the titer of trypsin was increased 6.71-fold.

Improved Production of Active Streptomyces griseus Trypsin with a Novel Auto-Catalyzed Strategy

N-terminal sequences play crucial roles in regulating expression, translation, activation and enzymatic properties of proteins. To reduce cell toxicity of intracellular trypsin and increase secretory expression, we developed a novel auto-catalyzed strategy to produce recombinant trypsin by engineering the N-terminus of mature Streptomyces griseus trypsin (SGT). The engineered N-terminal peptide...

P-65: Effective Parameters on the Bovine Follicle Stimulating Hormone Expression in The Pichia Pastoris System

Background: Bovine follicle-stimulating hormone (bFSH) is a heterodimer hormone that consists of a common -subunit which noncovalently associated with the hormone-specific -subunit. During the past 15 years, the methylotrophic yeast Pichia pastoris has become an important host organism for recombinant protein production because it is able to use methanol as a sole carbon and energy source. Th...

Improvement in the downstream processing of rhGH production in Pichia pastoris

Production of human proteins in Pichia pastoris has significant advantages. However, there is still need for improvement in various stages of its downstream processing like clarification and purification. In fact downstream processes are usually the most critical part of production of biotech products. This work aimed to evaluate the effect of two steps added to the downstream processes ...

P-205: Production of Recombinant Fish FSH Hormone in Pichia Pastoris

Background: Follicle-stimulating hormone (FSH) belongs to the family of glycoprotein hormones that composing alpha and beta subunits with non-covalently bonds. This hormone involve in regulation of the reproductive processes such as gamete generation and follicular growth. Injection of the hormone in most of fish species increases 17 beta-estradiol production by ovarian tissue and also stimulat...
