Proteomic analysis of the bacteriocin thuricin 17 produced by<i>Bacillus thuringiensis</i>NEB17
Bibliographic record
Abstract
Thuricin 17 is a recently discovered bacteriocin produced by Bacillus thuringiensis NEB17. The objective of this work was to conduct a proteomic analysis of this bacteriocin. The partial N- and C-terminal amino-acid sequences of thuricin 17 have now been determined using the Edman degradation and matrix-assisted laser desorption ionization-quadrapole time of flight mass spectrometry (MS)/MS. A hydrophobic cluster analysis indicates that thuricin 17 contains a hydrophobic region, potentially corresponding to a membrane associated domain. Based on time of production, this bacteriocin may be produced as a secondary metabolite. Interestingly, thuricin 17 shares the same N-terminal sequence, DWTXWSXL, with a previously reported bacteriocin, Bacthuricin F4, produced by B. thuringiensis ssp. kurstaki strain BUPM4. This is the first time two bacteriocins from different Bacillus species have been shown to share similar N-terminal sequences.

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.
