Figure Lengend Snippet: (A) Schematic representation of the different constructs that were generated in this study. Due to toxicity and/or production issues, only constructs 1, 2, 6, 7 and 8 were further used for BioID analyses. (B) Anti-HA Western blot analysis of total lysates from two independent clones of Msm mc²155 transformed with pMV361_ Nter (truncated), pMV361_ mmpL11 (full-length), pMV361_ Nter-birA or pMV361_ mmpL11-birA , as indicated. (C) OD600nm values at 16 and 40 h from cultures of Msm mc²155 transformed with empty pMV361 (in black), pMV361_ birA (in red), pMV361_ Nter (in green), pMV361_ mmpL11 (in blue), pMV361_ Nter-birA (in orange) or pMV361_ mmpL11-birA (in purple). (D) and (E) Western blot analyses using anti-HA antibodies or HRP-conjugated streptavidin of biotinylated proteins from total lysates of Msm mc²155 transformed with pMV361, pMV361_ birA , pMV361_ Nter , pMV361_ Nter-birA , pMV361_ mmpL11 or pMV361_ mmpL11-birA , after enrichment on streptavidin beads. The molecular size markers (M) with their respective sizes expressed in kDa are shown on the left. The positions of MmpL11-BirA (140 kDa), Nter-BirA (110 kDa) and BirA (37 kDa) are indicated by the short horizontal bars. Images are representative of three independent experiments.

Article Snippet: Searches were performed with a mass measurement tolerance of 10 ppm for precursor ions and 0.02 Da for fragment ions, against a composite target-decoy database constructed using a Msm mc2155 UniProt database (strain ATCC 700084/mc(2)155, taxo 246196, July 20172021, 12666 entries) fused with recombinant trypsin and a list of classical contaminants (118 entries).

doi: 10.1016/j.crmicr.2025.100535

Figure Lengend Snippet: Membrane integrity or damage and morphology of E. coli following exposure to various concentrations of the NCR169C 17–38 peptide. (A) E. coli cells were stained with SYTO 9 and PI, and pictures were taken with confocal microscope; scale bar: 10 µm. (B) Cells were treated with the peptide in the absence of fluorescent dyes and imaged using a scanning electron microscope; scale bar: 1 µm. (C) Monitoring of PI uptake in E. coli treated with a series of concentrations of NCR169C 17–38 in Hidex Plate reader. RFU (535/616) = Relative Fluorescence Units (excitation/emission wavelengths). 0.8 µM Polymyxin B (PMB) was used as a control.

Article Snippet: The trimmed samples were aligned to the E. coli ATCC_8739 genome database using STAR ( ) as described by ( ; supplementary Table 37).
