    Abstract: Vectors for producing polypeptides heterologous to prokaryotes are described comprising, along with the polypeptide-encoding nucleic acid, anti-termination nucleic acid that inhibits intragenic transcription termination with a non-lambda promoter therefor and/or nucleic acid encoding a GreA or GreB protein and a promoter therefor. Also described are processes for producing a heterologous polypeptide in prokaryotic host cells utilizing such elements to improve the quality and/or quantity of heterologous polypeptide produced.

    Abstract: The instant invention discloses the unexpected result that mutant signal sequences with reduced translational strength provided essentially complete processing and high levels of expression of a polypeptide of interest as compared to wild type signal sequences, and that many mammalian polypeptides require a narrow range of translation levels to achieve maximum secretion. A set of signal sequence vectors provides a range of translational strengths for optimizing expression of a polypeptide of interest.
