Isolation and transcriptional regulation of the<i>Kluyveromyces lactis</i><i>FBA1</i>(fructose-1,6-bisphosphate aldolase) gene
Bibliographic record
Abstract
Cloning and transcriptional regulation of the KlFBA1 gene that codes for the class II fructose-1,6-bisphosphate aldolase of the yeast Kluyveromyces lactis are described. KlFBA1 mRNA diminishes transiently during the shift from hypoxic to fully aerobic conditions and increases in the reversal shift. This regulation is mediated by heme since expression was higher in a mutant defective in heme biosynthesis. KlFBA1 transcription is not induced by calcium-shortage, low temperature, or at stationary phase. These data suggest that KlFBA1 plays a role in the balance between oxidative and fermentative metabolism and that this gene is differentially regulated in K. lactis and Saccharomyces cerevisiae, i.e., a respiratory vs. fermentative yeast.

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.
