Abstract
The terminal dipeptide, D-Ala-D-Ala, of the peptidoglycan precursor UDPMurNAc-pentapetide is a crucial building block involved in peptidoglycan cross-linking. It is synthesized in the bacterial cytoplasm by the enzyme d-alanine:d-alanine ligase (Ddl). Structure-based virtual screening of the NCI diversity set of almost 2000 compounds was performed with a DdlB isoform from Escherichia coli using the computational tool AutoDock 4.0. The 130 best-ranked compounds from this screen were tested in an in vitro assay for their inhibition of E. coli DdlB. Three compounds were identified that inhibit the enzyme with K(i) values in micromolar range. Two of these also have promising antibacterial activities against Gram-positive and Gram-negative bacteria.

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 it
