Role of the ompT mutation in stimulated decrease in colony-forming ability due to intracellular protein aggregate formation in Escherichia coli strain BL21.

Abstract excerpt

Recently we found that the cells of Escherichia coli strain BL21 producing a fusion protein, GST-Sup35NM, show a much more rapid decrease in colony-forming ability in the stationary phase than control cells. In this study, it was found that an extract of the cells producing GST-Sup35NM forms fibrous protein polymers containing GST-Sup35NM. In the course of the study, we realized that strain BL21 carried the ompT...
