The IntI-Like Tyrosine Recombinase of<i>Shewanella oneidensis</i>Is Active as an Integron Integrase
Bibliographic record
Abstract
We have found an integron-like integrase gene and an attI site in Shewanella oneidensis as part of a small chromosomal integron. We have cloned this gene and tested the ability of the integrase to excise cassettes from various integrons. Most cassettes flanked by two attC sites are readily excised, while cassettes in the "first" position, with an attI1 or attI3 site on one end, are not excised. An exception is a cassette with attI2 on one end. The attI2 site, from Tn7, has greater similarity to the attI site adjacent to the integrase of S. oneidensis than do attI1 or attI3. We cloned the attI site of S. oneidensis and observed the integration of two different cassettes. We have, therefore, demonstrated the function of this integron-like integrase.
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.
