Abstract excerpt
In comparison to stringent (relA+) controlled Escherichia coli cells, relaxed (relA) controlled E. coli cells excreted more recombinant beta-lactamase into the culture medium. The analysis of the composition of phospholipid fractions of the cells yielded increased levels of phosphatidylserine in relaxed controlled cells. We added various phospholipid vesicles to growing cells in order to influence the excretion...
