Abstract
3'-Aminoglycoside kinase type IIIa [APH(3')-IIIa] catalyzes the transfer of gamma-phosphate from ATP to the 3'-hydroxyl of many aminoglycoside antibiotics, abolishing their bactericidal effects. Despite very low sequence identity, APH(3')-IIIa and eukaryotic protein kinases share structural and functional similarities, including a sensitivity to isoquinolinsulfonamide-type inhibitors. APH(3')-IIIa has been cocrystallized with CKI-7, a casein kinase 1 inhibitor. These crystals were grown using PEG 3000 as precipitant and required consecutive cycles of microseeding. Data were collected to 2.5 A. The crystals belong to space group P2(1)2(1)2(1), with unit-cell parameters a = 49.84, b = 91.90, c = 131.2 A.

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 it
