Abstract

fetched live from OpenAlex

T6SS is capable of delivering effectors that could attack substrates found either in the periplasm or cytosol of target bacteria. Additionally, we found that effectors VgrG3 and TseL, despite lacking a classical Sec or TAT secretion signal, were able to reach the periplasm when expressed in the bacterial cytosol. This effector trafficking likely represents an evolutionary strategy for T6SS effectors to reach their intended substrates regardless of which subcellular compartment in the target cell they happen to be delivered to by the T6SS apparatus.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
