A family portrait: structural comparison of the Whirly proteins from<i>Arabidopsis thaliana</i>and<i>Solanum tuberosum</i>
Bibliographic record
Abstract
DNA double-strand breaks are highly detrimental genomic lesions that routinely arise in genomes. To protect the integrity of their genetic information, all organisms have evolved specialized DNA-repair mechanisms. Whirly proteins modulate DNA repair in plant chloroplasts and mitochondria by binding single-stranded DNA in a non-sequence-specific manner. Although most of the results showing the involvement of the Whirly proteins in DNA repair have been obtained in Arabidopsis thaliana, only the crystal structures of the potato Whirly proteins WHY1 and WHY2 have been reported to date. The present report of the crystal structures of the three Whirly proteins from A. thaliana (WHY1, WHY2 and WHY3) reveals that these structurally similar proteins assemble into tetramers. Furthermore, structural alignment with a potato WHY2-DNA complex reveals that the residues in these proteins are properly oriented to bind single-stranded DNA in a non-sequence-specific manner.

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.
