Expression of the<i>cry11A</i>gene of<i>Bacillus thuringiensis</i>ssp.<i>israelensis</i>in<i>Saccharomyces cerevisiae</i>
Bibliographic record
Abstract
The complete cry11A region gene of Bacillus thuringiensis ssp. israelensis was fused in frame to the 3' end of the GST gene under the control of the Saccharomyces cerevisiae HXK1 promoter. The fusion protein GST-cry11A was expressed in S. cerevisiae strain AMW13C+. The fusion gene GST-cry11A was expressed when yeast cells were grown on galactose and a nonfermentable medium containing ethanol as carbon and energy source. When the cells were grown in glucose, mannose, fructose, or glycerol as carbon sources, the GST-cry11A gene was repressed. Thus, a regulated expression in accordance with the regulatory activity of the HXK1 gene promoter has been detected. The GST-cry11A fusion protein was detected in the transformed yeasts as a soluble protein. The fusion protein was purified by affinity chromatography using glutathione-Sepharose beads. Cell-free extracts from transformed yeasts grown in ethanol-containing culture media showed insecticidal activity against third-instar Aedes aegypti larvae. This insecticidal activity was increased about 4-fold when the purified fusion protein was assayed.

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.
