Preliminary X-ray crystallographic studies of UDP-glucose-4-epimerase from<i>Aspergillus nidulans</i>
Bibliographic record
Abstract
UDP-glucose-4-epimerase (GALE) from Aspergillus nidulans was overexpressed in Escherichia coli, purified via His-tag affinity chromatography and cocrystallized with UDP-galactose using the microbatch method. The crystals diffracted to 2.4 Å resolution using synchrotron radiation on the Canadian Light Source 08ID-1 beamline. Examination of the data with d*TREK revealed nonmerohedral twinning, from which a single lattice was ultimately extracted for processing. The final space group was found to be C2, with unit-cell parameters a = 66.13, b = 119.15, c = 161.42 Å, β = 98.48°. An initial structure solution has been obtained via molecular replacement employing human GALE (PDB entry 1hzj) as a template model.

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.
