Purification, crystallization and preliminary X-ray diffraction analysis of the Whirly domain of StWhy2 in complex with single-stranded DNA
Bibliographic record
Abstract
StWhy1 and StWhy2 are members of the Whirly family of single-stranded DNA (ssDNA) binding proteins. To understand the mode of binding of the Whirly proteins to single-stranded DNA, crystals of the Whirly domains of both StWhy1 and StWhy2 in complex with single-stranded DNA were obtained by the hanging-drop vapour-diffusion method. The diffraction patterns of the StWhy1-ssDNA complex crystals displayed severe anisotropy and were of low resolution, making them unsuitable for structure determination. In contrast, the crystals of the StWhy2-ssDNA complex diffracted isotropically to 2.20 A resolution. The crystallization and data collection to 2.20 A resolution of StWhy2 in the free form are also reported.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
