Plant nucleoside diphosphate kinase 1: A housekeeping enzyme with moonlighting activity
Bibliographic record
Abstract
Nucleoside diphosphate kinase (NDPK) catalyzes the interconversion of nucleoside diphosphates and triphosphates using ATP as phosphate donor. This housekeeping enzyme is present in several subcellular compartments. The main isoform (NDPK1) is located in the cytosol and is highly expressed in meristems and provascular tissues. The manipulation of NDPK1 levels in transgenic potato roots demonstrates that this enzyme plays a key role in the transfer of energy between the cytosolic adenine and uridine nucleotide pools and in the distribution of carbon between starch and cellulose. Modulation of the expression of NDPK1 also alters the homeostasis of root respiration, glycolytic flux, reactive oxygen species production and growth. Herein, we propose a model summarizing the effects of the manipulation of NDPK1 levels on root metabolism. The model also accounts for G-quadruplex DNA binding, a moonlighting activity recently attributed to NDPK1, which possibly contributes to the metabolic phenotype of transgenic roots.

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.
