Characterization and functional expression in yeast of a cDNA encoding NADP-dependent malic enzyme from castor oil seed
Bibliographic record
Abstract
A cDNA encoding NADP-dependent malic enzyme was isolated from castor bean (Ricinus communis L.) endosperm. The 2362-bp cDNA encodes a 641 amino acid protein, which is predicted to have a 50 amino acid chloroplast transit peptide. Southern blotting revealed a single copy of the gene. Recombinant protein expression confirmed that the cDNA encodes a NADP-dependent malic enzyme; both Western blotting and enzyme assays detected NADP-dependent malic enzyme. Removal of the transit peptide in the recombinant protein did not affect the pH optimum of the enzyme, but it did result in an increased specific activity.Key words: Ricinus communis, NADP-dependent malic enzyme (NADP-ME), fatty acid biosynthesis, leucoplast, recombinant protein expression, transit peptide.
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.
