Involvement of mitochondrial ferredoxin and Cox15p in hydroxylation of heme O
Bibliographic record
Abstract
Cox15p is essential for the biogenesis of cytochrome oxidase [Glerum et al., J. Biol. Chem. 272 (1997) 19088-19094]. We show here that cox15 mutants are blocked in heme A but not heme O biosynthesis. In Schizosaccharomyces pombe COX15 is fused to YAH1, the yeast gene for mitochondrial ferredoxin (adrenodoxin). A fusion of Cox15p and Yah1p in Saccharomyces cerevisiae rescued both cox15 and yah1 null mutants. This suggests that Yah1p functions in concert with Cox15p. We propose that Cox15p functions together with Yah1p and its putative reductase (Arh1p) in the hydroxylation of heme O.

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.
