A cell wall protein (YqgA) is genetically related to the cell wall-degrading <scp>dl</scp>-endopeptidases in <i>Bacillus subtilis</i>
Bibliographic record
Abstract
The Gram-positive bacterium Bacillus subtilis has a thick cell wall. The cell wall contains various proteins, both for secretion and for peptidoglycan (PG) maintenance. Penicillin-binding proteins for PG synthesis, PG hydrolases (autolysins), and regulator proteins for the autolysins are the known components of the PG maintenance system. YqgA was identified as an abundant protein attached to the cell wall of B. subtilis through a proteomics analysis. The YqgA protein was localized at cell division sites during the transition period between the exponential and the stationary phases. YqgA localization was affected by mutations in the dl-endopeptidases (DLEPases), which are the autolysins involved in cell morphogenesis. Furthermore, yqgA mutations on a background of defective DLEPases led to delays in cell growth and cell morphological changes. These results demonstrate that yqgA is genetically related to the genes encoding DLEPases involved in cell morphogenesis.

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.
