Iron facilitates the RetS-Gac-Rsm cascade to inversely regulate protease IV (piv) expression via the sigma factor PvdS in Pseudomonas aeruginosa.

Environmental microbiology - 1 Dec 2020

Abstract excerpt

Pseudomonas aeruginosa produces several proteases, such as an elastase (LasB protease), a LasA protease, and protease IV (PIV), which are thought as significant virulence factors during infection. Regulators of LasA and LasB expression have been identified and well characterized; however, the molecular details of this regulation of protease IV (PIV) remained largely unknown. Here, we describe the interaction...
