Webbcontained an inverted repeat partially covering the promoter box, was shown to be essential for VraSR-mediated induction by cell wall stress. Interestingly, the induction or overexpression of tcaA did not contribute further to teicoplanin susceptibility, suggesting that small amounts of TcaA, such as those present under Webbunder the transcriptional control of the tetA promoter sys-tem. Large-scale production benefits from the anhydro-tetracycline-inducible system because of the lower costs for the inducer compared to IPTG and the tightly regulated expression of the recombinant antibody fragments. The Strep-tag purification technology facilitates the isolation
