This study identifies the functional interplay between PBP1A and LdtJ in Acinetobacter baumannii, showing that disrupting their coordination weakens the cell envelope and increases colistin resistance.

The paper shows that disrupting phospholipid homeostasis in Gram-negative bacteria enables LOS-deficient, colistin-resistant variants by altering outer membrane structure and peptidoglycan synthesis.

This study shows that the Tol-Pal system in Acinetobacter baumannii is conditionally required for envelope organization under specific environmental stresses but not under standard lab conditions.

This study investigates the distinct roles of DD-peptidases in Acinetobacter baumannii, showing their unique contributions to cell morphology, growth, and peptidoglycan composition, with implications for antimicrobial therapy.
