Inhibition of <i>Helicobacter pylori</i> Glu‐t<scp>RNA<sup>G</sup></scp><sup>ln</sup> amidotransferase by novel analogues of the putative transamidation intermediate
Bibliographic record
Abstract
Glutaminyl‐t RNA G ln in Helicobacter pylori is formed by an indirect route requiring a noncanonical glutamyl‐t RNA synthetase and a t RNA ‐dependent heterotrimeric amidotransferase (AdT) Gat CAB . Widespread use of this pathway among prominent human pathogens, and its absence in the mammalian cytoplasm, identify AdT as a target for the development of antimicrobial agents. We present here the inhibitory properties of three dipeptide‐like sulfone‐containing compounds analogous to the transamidation intermediates, which are competitive inhibitors of AdT with respect to Glu‐t RNA G ln . Molecular docking revealed that AdT inhibition by these compounds depends on π–π stacking interactions between their aromatic groups and Tyr81 of the GatB subunit. The properties of these inhibitors indicate that the 3′‐terminal adenine of Glu‐t RNA G ln plays a major role in binding to the AdT transamidation active site.

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; a candidate call from one teacher head, not a consensus.
