Verification of the toolbox by the secretory overproduction of two difficult-to-express proteins.

Construction of a versatile Bacillus subtilis gene expression toolbox.

subtilis host-vector system for the extracellular production of two eukaryotic proteins with biotechnological relevance. This study demonstrates the suitability of the prokaryotic B. subtilis toolbox fermentation strategies were developed and tested. For the best performing Sox and interleukin, overproducing and secreting variants of these new B. These included the sulfhydryl oxidase Sox from Saccharomyces cerevisiae, which forms reactive hydrogen peroxide and undesired cross-linking of functional proteins, and the human interleukin-1β, a pro-inflammatory cytokine. The appropriateness of this alternative expression platform was tested for the overproduction of two difficult-to-produce eukaryotic model proteins. subtilis toolbox is based on a tailor-made, clean deletion mutant strain, which is protease and sporulation deficient and exhibits reduced autolysis and secondary metabolism. This toolbox comprises a set of 60 expression vectors, which combine two promoter variants, four strong secretion signals, a translation-enhancing downstream box, and three plasmid backbones. In this study, we designed a novel Bacillus subtilis expression toolbox, which allows the overproduction and secretion of potentially toxic enzymes.

In order to find the right heterologous gene expression strategy, suitable host-vector systems, which combine different genetic circuits, are useful. Therefore, versatile flexible expression systems for their functional overproduction are required. proteins in biotechnological applications are highly diverse. 12 Institute of Marine Biotechnology, Walther-Rathenau-Str. 11 Pharmaceutical Biotechnology, Institute of Pharmacy, University of Greifswald, Felix-Hausdorff-Str.1 Institute of Technical Microbiology, Hamburg University of Technology, Kasernenstr. 10 Miltenyi Biotec GmbH, Robert-Koch-Str.8 Department of Biotechnology and Food Science, NTNU, Sem Sælands vei 6, 7034, Trondheim, Norway.7 Bioprocess Center, Eppendorf AG, Rudolf-Schulten-Str.6 Department of Biomolecular Chemistry, Leibniz Institute for Natural Product Research and Infection Biology, HKI, Beutenbergstr.5 Institute of Applied Microbiology - iAMB, Aachen Biology and Biotechnology - ABBt, RWTH Aachen University, Worringerweg 1, 52074, Aachen, Germany.4 Enzymicals AG, Walther-Rathenau-Straße 49a, 17489, Greifswald, Germany.3 Institute of Marine Biotechnology, Walther-Rathenau-Str.2 Pharmaceutical Biotechnology, Institute of Pharmacy, University of Greifswald, Felix-Hausdorff-Str.1 Institute of Technical Microbiology, Hamburg University of Technology, Kasernenstr.
