Tunable recombinant protein expression in E. coli: Promoter systems and genetic constraints

Abstract

Tuning of transcription is a promising strategy to overcome challenges associated with a non-suitable expression rate like outgrowth of segregants, inclusion body formation, metabolic burden and inefficient translocation. By adjusting the expression rate-even on line-to purposeful levels higher product titres and more cost-efficient production processes can be achieved by enabling culture long-term stability and constant product quality. Some tunable systems are registered for patents or already commercially available. Within this contribution, we discuss the induction mechanisms of various Escherichia coli inherent promoter systems with respect to their tunability and review studies using these systems for expression tuning. According to the current level of knowledge, some promoter systems were successfully used for expression tuning, and in some cases, analytical evidence on single-cell level is still pending. However, only a few studies using tunable strains apply a suitable process control strategy. So far, expression tuning has only gathered little attention, but we anticipate that expression tuning harbours great potential for enabling and optimizing the production of a broad spectrum of products in E. coli.

  • Protein secretion can be effectively modulated at the transcriptional level by modifying the promoters in the expression vector.

    “Protein secretion can be effectively modulated at the transcriptional level by modifying the promoters in the expression vector [145].”

    From Evolution of Escherichia coli Expression System in Producing Antibody Recombinant Fragments (2020) · cites this paper as [145]

    The Introduction describes tuning recombinant protein expression in E. coli through promoter systems, and the prpBCDE operon section reports different expression levels with different promoter-based vectors. These passages concern protein expression, not secretion; the cited paper does not establish that modifying vector promoters effectively modulates secretion. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
