Abstract
Escherichia coli export the protein YebF into the extracellular medium by a two-step process. However, as no general outer membrane protein secretion system common to all E. coli strains has been reported, the mechanism of export has remained unclear. Herein, we identify the outer membrane proteins OmpF, OmpC, and OmpX as central to the YebF export mechanism using both genetic and planar lipid bilayer experiments. The nuclear magnetic resonance structural ensemble of YebF reveals a cystatin-like fold consisting of a structured core and an extended dynamic surface in a state of conformational exchange. This surface, conserved throughout YebF orthologs of Enterobacteriaceae, may facilitate the porin-mediated transport of YebF as amino acid substitutions of dynamic residues reduced secretion to the extracellular medium. Our results demonstrate that OmpF and OmpC not only operate to import ions and protein toxins but may also contribute to the export of the YebF protein family.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
