“…This absence of stress response induction is consistent with what has been observed for a variety of integral membrane proteins in a very recently published study (Gubellini et al, 2011). Overexpression of NTR1(D03) together with nlpDΔ(349-380), however, resulted in a significant increase in transcription from P3rpoH, PftsH, and PppiD, promoters (3.5-, 2.9-, and 2.7-fold, respectively) compared to the empty plasmid control and, to a lesser extent, from the PppiA, PbolA and Plon promoters (2.3-, 2.3-, and 2.1-fold, respectively) (Figure 4).…”
