High-Throughput Screening Identifies Three Inhibitor Classes of the Telomere Resolvase from the Lyme Disease Spirochete
Bibliographic record
Abstract
Lyme disease, the most common vector-borne zoonosis in North America, is caused by the spirochetal pathogen Borrelia burgdorferi. The telomere resolvase encoded by this organism (ResT) promotes the formation of covalently closed hairpin ends on the linear DNA molecules of B. burgdorferi through a two-step transesterification. ResT is essential for survival and is therefore an attractive target for the development of highly specific antiborrelial drugs. To identify ResT inhibitors, a novel fluorescence-based high-throughput assay was developed and used to screen a library of 27,520 small-molecule drug-like compounds. Six confirmed inhibitors of ResT, with 50% inhibitory concentrations between 2 and 10 muM, were identified. The inhibitors were characterized further and were grouped into three distinct classes based on their inhibitory features. The high-throughput screening assay developed in this paper, along with the six inhibitory compounds identified, provides a starting point for the future development of novel antiborrelial drugs as well as small-molecule inhibitors that will be helpful for the further dissection of the reaction mechanism.

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