摘要:
Disclosed herein are nucleic acid constructs and expression vectors for enhancing the production of recombinant polypeptides/proteins, and methods for the massive production of recombinant polypeptides/proteins, in which a first nucleic acid sequence encoding thioredoxin and a second nucleic acid sequence encoding hemoglobin are cloned into a host cell, thereby enhancing the capability of the thus formed recombinant host cell in producing a selected gene product, and thereby assisting said recombinant host cell in relieving intracellular stress due to the overproduction of said gene product.
