Relationship between time to positivity and bacterial load for LAMP detection of S. pneumoniae , S. aureus , and H. influenzae . As the bacterial concentration decreased, the time required for detection increased across all three pathogens. For S. pneumoniae , high concentrations produced a clear positive result within 35 min. However, concentrations near the LoD (10 4 and 10 3 CFU/mL) required more than 55 min to be considered positive. Similarly, S. aureus showed a positive signal at 35 min when tested at high concentrations, whereas lower concentrations (around 10 4 CFU/mL) required over 45. In the case of H. influenzae , the highest concentration yielded a visible positive reaction at 25 min, while lower concentrations needed up to 45 min. Transition phase: In all cases, there was a stage where tubes began to show a greenish signal, indicating the onset of positivity, although the color had not yet fully developed to a strong green signal.

(A) Workflow for determining homology of Mdps: structural domains of the Mdps were determined and excised from the AlphaFold2 predictions. These domains were used to perform structure-based homology searches using DALI and FoldSeek. Shown is the Mdp444 N-ter SurA domain (teal) aligned to pdb: 6VJ4 (grey), the N-ter PPIC domain (salmon) aligned to afdb: AF-A0A3M6KDR7-F1-v4 (grey), the C-ter SurA domain (blue) aligned to pdb: 5HTF (grey), and the C-ter PPIC domain (pink) aligned to afdb: AF-A0A5C6BMD5 (grey). (B) The domain arrangement determined from the structural homology searches shows that all three Mdps have an N- and C-terminal structural unit both consisting of a SurA domain followed by a PPIC domain. The white boxes indicate insertions. (C) Superposition of SurA domain from the Mdp444 N-terminal SurA domain (teal) and PrsA from Bacillus anthracis (pdb 6VJ4; grey).

The corresponding residues are indicated on the N-terminal PPIC domain of Mdp444, followed by a superposition of the two, showing that the catalytic and substrate binding residues are conserved. (E-F) A reconciliated phylogenetic tree, showing the evolutionary events of (E) the Mdp family of proteins, and (F) MPN523 in Mycoplasma , and other bacteria. The black outline indicates the species tree, and the colored lines indicate the proteins. The lines are colored to indicate whether (E) the catalytic residues are conserved (orange) or not (blue) for the Mdps, or (F) whether the CXXC motif is conserved (yellow) or not (green).

(A) Schematic model of the translocation cycle in M. pneumoniae . SecA binding primes the complex for translocation, involving reorganization of the SecDF-SecYEG architecture, and interactions with the extracellular dome proteins. (B) Structural models of the different dome-complexes. In the pre-translocation state, the SecA-unbound dome is in a resting state. Association of SecA with a substrate initiates translocaiton. Co-translational translocation can either happen in a flexible form with ribosome and dome associated via the nascent peptide or directly through physical coupling of the two macromolecular complexes, forming a supercomplex.

(B) Detection of IL-4 in lung tissue homogenate supernatants. (C) Detection of IFN-γ in lung tissue homogenate supernatants. (D) Detection of IL-10 in lung tissue homogenate supernatants. Data are presented as mean ± 95% CI. Statistical significance tested by one-way ANOVA test (* P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001).
