The importance of yeast Alr proteins in cadmium detoxification as indicated by particle‐induced x‐ray emission and phenotypic analyses
Bibliographic record
Abstract
Abstract One gene in Saccharomyces cerevisiae, ALR1 , encodes a transmembrane protein involved in the transport of Mg 2+ into cells. Overexpression of this gene changes the tolerance of S. cerevisiae to several metal cations. In order to study the cellular uptake mechanism of metal cations in S. cerevisiae , an accurate determination of the metals present in the cells is needed. In this work, particle‐induced x‐ray emission (PIXE) was employed to analyze the intracellular metal content after cell exposure to cadmium. To that end, a specific method for sample preparation was developed. The samples were irradiated with a 2 MeV proton beam, while the induced x‐rays were detected with a high‐purity germanium detector. The PIXE results for cadmium‐exposed ALR1 mutant and wild‐type yeast cells suggest that Alr1p has a central role in the cell survival process in a cadmium‐rich environment.

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.
