Methods for producing polypeptides in respiratory-deficient cells

The present invention relates to methods of producing a polypeptide, comprising: (a) introducing into a respiratory-defective mutant of a cell (i) one or more first nucleic acid sequences which complement the respiratory defect and (ii) a second nucleic acid sequence which encodes the polypeptide; (...

More Information
Summary:The present invention relates to methods of producing a polypeptide, comprising: (a) introducing into a respiratory-defective mutant of a cell (i) one or more first nucleic acid sequences which complement the respiratory defect and (ii) a second nucleic acid sequence which encodes the polypeptide; (b) cultivating the cell containing the first and second nucleic acid sequences in a culture medium under aerobic conditions suitable for expression of the first and second nucleic acid sequences; and (c) isolating the polypeptide from the cultivation medium of the cell. The present invention also relates to methods for disrupting a gene in a respiratory-deficient mutant cell. The present invention further relates to respiratory-deficient mutant cells and methods for obtaining such mutant cells.
