Identification and characterization of an LCAT‐like <i>Arabidopsis thaliana</i> gene encoding a novel phospholipase A
Bibliographic record
Abstract
A previously uncharacterized Arabidopsis lecithin:cholesterol acyltransferase (LCAT) family gene (At4g19860) was functionally expressed in yeast, where it was demonstrated to encode a novel cytosolic and calcium-independent phospholipase A with preferences for the sn-2 position. This enzyme shows optimal activity at pH 5.0, exhibits a headgroup specificity for phosphatidylcholine>phosphatidic acid>phosphatidylethanolamine>phosphatidylglycerol>phosphatidylserine and has an acyl chain specificity for oleoyl>linoleoyl>ricinoleoyl. The expression of AtLCAT-PLA inhibited yeast cell growth and fatty acid accumulation. AtLCAT-PLA transcript in Arabidopsis was detected at high levels in roots and siliques.
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.
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.
