Abstract

fetched live from OpenAlex

The related antibiotics formylaminooxyvinylglycine (FVG) and aminoethoxyvinylglycine (AVG) have been shown to have activity against the fire blight pathogen Erwinia amylovora ; however, E. amylovora can develop spontaneous resistance to these antibiotics. By comparing the genomes of mutants to those of the wild type, we found that inactivation of the l -asparagine transporter conferred resistance to FVG, while inactivation of the l -arginine transporter conferred resistance to AVG. We also show that the transporter encoded by the FVG biosynthetic cluster can confer resistance to both FVG and AVG. Our work indicates the important role that amino acid transporters play in the import of antibiotics and highlights the possible utility in designer antibiotics that enter the bacterial cell through amino acid transporters.

Full frame distilled prediction

Teacher imitation

Not 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.
