Method for improving expression quantity of pichia pastoris foreign protein by using mercaptan peroxidase

ActiveCN103898142AContributes to correct conformational formationPromote secretionVector-based foreign material introductionPichia pastorisBiotechnology
The invention discloses a method for improving the expression quantity of a pichia pastoris foreign recombinant protein by using mercaptan peroxidase as a cofactor aiming at improving the preparation capability of the pichia pastoris foreign recombinant protein, belonging to the field of biochemical engineering. The method comprises the steps of connecting a mercaptan peroxidase gene with an inducible promoter or a constitutive promoter from pichia pastoris or saccharomyces cerevisiae to construct a gene expression vector, and transferring the gene expression vector to a methanol induced pichia pastoris strain for expressing the foreign recombinant protein to perform co-expression or over-expression, wherein the mercaptan peroxidase gene serving as a global control gene of oxidation reduction stress response improves the expression quantity of the foreign recombinant protein in the methanol induced pichia pastoris under the control effects of the promoter of different strengths and the transcriptional level of a gene copy number. The invention provides a new method for improving the capability of producing recombinant protein by cells and the bio-reaction efficiency, which has an important value for strengthening a biotechnology process.
