Biodegradation of cyclic amines by a<i>Pseudomonas</i>strain involves an amine mono-oxygenase
Bibliographic record
Abstract
Pseudomonas putida O1G3 catalyzes the degradation of pyrrolidine and piperidine. This strain can use these compounds as the sole source of carbon, nitrogen, and energy. When the cyclic amines were used as the growth substrates, the synthesis of a soluble heme amine mono-oxygenase was induced in this bacteria. This observation was confirmed by spectrophotometric analysis and specific inhibitor. This mono-oxygenase is a NADH-dependent enzyme and catalyzes the cleavage of the C-N bond of the pyrrolidine and piperidine ring by a mechanism similar to a N dealkylation. This reaction could be followed by ring cleavage to form gamma-aminobutyraldehyde oxidized to gamma-aminobutyrate. Further investigations to purify the heme-containing mono-oxygenase are in progress.

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.
