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.

This study uses CRISPRi to screen B. subtilis genes across 150 stress conditions, revealing new roles for conserved firmicute genes in protein secretion, cell wall homeostasis, and bacterial competition.

This study shows Trichomonas vaginalis phagocytoses Lactobacillus jensenii via pseudopodia-independent mechanism and secretes TvGH25 lysozyme to reduce bacterial counts.

This study investigates the role of PopZ in Zymomonas mobilis, finding it dispensable for growth but necessary for polar localization of ParB.

This paper confirms Zymomonas mobilis is polyploid and introduces a SacB-based counter-selection system for genome engineering.

This study shows that the lytic transglycosylase SleB in Zymomonas mobilis is crucial for cell fitness and stress tolerance through its role in peptidoglycan remodeling.

Vi-TIS improves TIS accuracy by excluding dead cells using PMA, enhancing essential gene identification and revealing new antibiotic susceptibility patterns in E. coli.

This study shows wall teichoic acids prevent nanoscopic pores in the cell wall by inhibiting PBP1 and promoting Rod complex activity, maintaining rod shape in Bacillus subtilis.

This paper identifies VdAve1, an antimicrobial effector from the fungal pathogen Verticillium dahliae, and shows it kills bacteria by binding lipoteichoic acid and disrupting plasma membranes.

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.

This paper identifies the pneumococcal S protein as essential for resisting host antimicrobials by coordinating cell wall modification and repair through interactions with PBP1a and PgdA.

This study identifies a conserved molecular toolkit in Trichomonas species acquired through lateral gene transfer, enabling interaction with microbiota and potentially influencing host inflammation.

This study identifies peptidoglycan remodelling as a mechanism to improve salt resilience in Zymomonas mobilis by modulating the protease CtpA and peptidoglycan endopeptidase MepM.

This study investigates the role of LdtJ in Acinetobacter baumannii, showing its impact on peptidoglycan integrity and outer membrane lipid asymmetry, with defects suppressed by disrupting the Mla pathway.

This paper identifies SddA, a periplasmic deacetylase that modulates daughter cell separation in E. coli by modifying denuded peptidoglycan strands, and links its function to amidase activation.

This study shows that weakening outer membrane-peptidoglycan interactions in E. coli enhances bile salt resistance by alleviating spatial constraints and reducing stress from UndPP-OAg intermediates.

This study shows that mecillinam affects the balance between surface area and volume synthesis in E. coli, leading to growth-rate dependent efficacy and lysis or sustained growth depending on the medium.
