The protein PA2854 (shown in red) in Pseudomonas aeruginosa links the outer-membrane protein OprI (shown in blue) to the cell wall (depicted in white), a process that is necessary for the health of the bacterium. (Graphic provided by the Mobashery Lab) Researchers at the University of Notre Dame and collaborators have discovered a key process for how the outer membrane of gram-negative bacteria attaches to the cell wall, advancing the understanding of how these bacteria frequently manifest resi
