The Role of Post‐Translational Enzyme Modifications in the Metabolic Adaptations of Phosphorus‐Deprived Plants
Bibliographic record
Abstract
Abstract Post‐translational modification ( PTM ) is the covalent alteration of a functional group of a specific amino acid residue within a particular protein. Diverse protein PTMs represent pivotal regulatory mechanisms that integrate signalling, development, gene expression, metabolism, and stress responses in plant and animal cells. These PTMs : (i) are often genetically predetermined, rapid, interconnected, and reversible; and (ii) can not only dramatically alter an enzyme's activity but may also generate specific PTM ‐dependent docking sites that influence its interactions with other proteins. The aim of this chapter is to highlight three crucial PTMs (phosphorylation, monoubiquitination, and glycosylation) and to provide examples of their participation in the in‐vivo function and control of several key enzymes that facilitate plant acclimatisation to soluble phosphate (Pi) ‐deficient soils. Pinpointing the impact of altered Pi supply on the prevalence, mechanisms and functions of enzyme PTMs will make an important contribution to the implementation of effective biotechnological strategies for engineering crops having enhanced P‐acquisition and P‐use efficiency.

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.
