Abstract Cell-free protein synthesis (CFPS) system is an ideal platform for fast and convenient research has been used macromolecular assembly, unnatural amino acid embedding, glycoprotein production, more. To realize the construction of efficient eukaryotic CFPS with advantages low cost short time, a based on yeast Pichia pastoris was built in this study. The internal ribosomal entry site (IRE...

Infectious bursal disease virus (IBDV) is the causative agent of Gumboro disease, an infectious disease of global economic importance in poultry. The expression of heterologous proteins in P.pastoris is fast, simple and inexpensive. In this study, VP2 encoding gene of classical D78 IBDV was amplified using reverse transcription (RT) polymerase chain reaction (PCR) and cloned into pPICZαA vector...

The rate-limiting enzyme in the mevalonic acid (MVA) pathway which can lead to triterpenoid saponin glycyrrhizic acid (GA) is 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR). In order to reveal the effect of copy number variation in the HMGR gene on the MVA pathway, the HMGR gene from Glycyrrhiza uralensis Fisch. (GuHMGR) was cloned and over-expressed in Pichia pastoris GS115. Six recombinant P...

Introduction: The development of an effective vaccine against Hepatitis C virus (HCV) is still a target of intensive vaccine research. The HCV envelope proteins E1 and E2 which can induce broadly neutralizing antibodies are the major candidate for this purpose. Different types of expression systems have been used to express these glycoproteins. In this study, an expression system using Pichia p...

background and objective: the outer membrane protein w ( ompw ) of vibrio cholerae is involved in stimulating the im- mune response via induction of protective immunity. it also plays an important role in bacterial pathogenesis by increasing the adaptability of pathogenic strains. in this study we aimed to clone v. cholerae ompw gene in the strain x-33 of pichia pastoris. materials and methods:...
