Molecular pathways induced by desiccation and starvation stresses in A. baumannii. desiccation and starvation stresses activate the two-component system BmfS/BmfR leading to the release of BmfR that acts as a transcriptional regulator. BmfR activates the expression of different genes, including those coding for the catalase KatE implicated in ROS detoxification, CsrA, an RNA-binding protein acting as a post-transcriptional regulator through modulation of the half-life of different mRnas, and the two hydrophilins DtpA and DtpB, acting as molecular chaperones that prevent protein denaturation. Denatured proteins that cannot be re-folded are degraded by the lon protease. Abbreviations: OM, outer membrane; P, periplasm; IM, inner membrane. Figure created with Biorender.
