| 摘要 |
The present invention relates to processes for recovering heterologous polypeptides from bacterial cells, including the periplasm and cytoplasm. The processes involve culturing the bacterial cells, which cells comprise nucleic acid encoding phage lysozyme and nucleic acid encoding a protein that displays DNA-digesting activity, wherein these nucleic acids are linked to a first promoter, and nucleic acid encoding the heterologous polypeptide, which nucleic acid is linked to a second promoter, under certain conditions to produce a broth lysate; and recovering accumulated heterologous polypeptide from the broth lysate. <IMAGE> |
