Abstract

fetched live from OpenAlex

We have isolated the genes for quinol oxidase from a deep-sea piezophilic bacterium, Shewanella violacea. Analysis of the deduced amino acid sequences of the cyo subunits showed that this oxidase has high similarity to Escherichia coli bo-type quinol oxidase. Northern blot analysis showed that these genes are expressed at a high level when the bacterium is grown at elevated pressure. Upstream in the cyo-operon, a sigma54-binding motif and an octamer sequence unit were found, suggesting that these elements may play a role in regulation of expression of the cyo-operon in response to changes in pressure.

Full frame distilled prediction

Teacher imitation

Not 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.
