The ATP-dependent protease ClpYQ degrades cell division proteins DivIVA and Mbl in <i>Bacillus subtilis</i>
Bibliographic record
Abstract
Abstract ATP-dependent proteases play key roles in bacterial protein quality control and regulation of cellular processes. ClpYQ and ClpXP are ATP-dependent proteases in the Gram-positive bacteria Bacillus subtilis . To date, no substrate proteins of B. subtilis ClpYQ have been characterized. The protease component encoded by clpQ is synthetically lethal with clpP and the two genes are non-essential individually, suggesting potentially redundant roles for ClpYQ and ClpXP. Previous quantitative proteomic data predicted that B. subtilis proteins DivIVA and Mbl, components of the divisome and elongasome respectively, are potential substrates of ClpYQ. The role of DivIVA and Mbl in cell division and elongation suggests a significant role of ClpYQ in regulating cell division through targeted degradation of key divisome and elongasome proteins. Here we confirm that DivIVA and Mbl are degraded by ClpYQ both in vitro and in vivo , and thus identify the first two substrates of ClpYQ in B. subtilis .

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.
