Ribosomal protein S1 plays a critical role in horizontal gene transfer by mediating the expression of foreign mRNAs
Bibliographic record
Abstract
ABSTRACT The emergence of multi-antibiotic resistant bacteria is one of the largest threats to global heath. This rise is due to the genomic plasticity of bacteria, allowing rapid acquisition of antibiotic resistance through the uptake of foreign DNA (i.e. horizontal gene transfer, HGT). This genomic plasticity is not limited to DNA from bacteria, highly divergent (trans-kingdom) mRNA have been reported to drive translation in E. coli . Trans-kingdom activity has been attributed to mRNA tertiary structure suggesting the bacterial translation machinery bottle-necks HGT, restricting the expression of foreign DNA. However, here we show that tertiary structure is not responsible for ribosome recruitment and that the translation efficiency is dependent on ribosomal protein S1 and an A-rich Shine-Dalgarno-like element. The S1-facilitated ability of ribosomes to identify and exploit A-rich sequences in foreign RNA highlights the important role that S1 plays in horizontal gene transfer, the robustness of canonical prokaryotic translation, and bacterial evolution.

Full frame machine prediction
Teacher imitationNot 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.
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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
