Vectors and transformed host cells for recombinant protein production at reduced temperatures

摘要

The invention relates to an expression vector, the nucleic acid sequence of which comprises a promoter that is capable of controlling, when the vector is in a bacterial host and the temperature is lowered to below about 20 DEG C., the production of recombinant peptide or protein encoded by a gene contained within the vector. The invention also relates to host cells containing the vectors and to a method of producing a recombinant protein.
