Abstract
We show here that the metK gene is essential to the growth of Escherichia coli K-12 and can be deleted only in the presence of a rescue plasmid carrying a functional metK gene. When metK expression was limited, genomic DNA methylation decreased and cell division was hampered. Through primer extension, the transcription start site of metK was located at 140 bp upstream of the translation start site. The frequently used metK84 mutant has been shown to carry an A(r)G transition in the -10 region of the metK promoter. This accounts for its low level of S-adenosylmethionine (SAM) synthetase and SAM deficiency.

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
