Protein phosphorylation in plant mitochondria
Bibliographic record
Abstract
Reversible phosphorylation of proteins is one of the most common regulatory mechanisms in eukaryotic cells and it can affect virtually any property of a protein. We predict that plant mitochondria possess 50–200 protein kinases (PKs), at least as many target proteins and 10–30 protein phosphatases although all will not be expressed at the same time in the same cell type or tissue. Presently available high‐throughput methods for the identification of phosphoproteins and their phosphorylation sites are first reviewed and a number of useful databases listed. We then discuss the known phosphoproteins, PKs and phosphatases in plant mitochondria and compare with yeast and mammalian mitochondria. Three case stories—respiratory chain complex I, pyruvate dehydrogenase and formate dehydrogenase—are briefly considered before a final treatment of mitochondrial protein phosphorylation in intracellular signal transduction and programmed cell death.
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.
