Additivity‐based design of the strongest possible turkey ovomucoid third domain inhibitors for porcine pancreatic elastase (PPE) and<i>Streptomyces griseus</i>protease B (SGPB)
Bibliographic record
Abstract
We describe here successful designs of strong inhibitors for porcine pancreatic elastase (PPE) and Streptomyces griseus protease B (SGPB). For each enzyme two inhibitor variants were designed. In one, the reactive site residue (position 18) was retained and the best residues were substituted at contact positions 13, 14, and 15. In the other variant the best residues were substituted at all contact positions except the reactive site where a Gly was substituted. The four designed variants were: for PPE, T(13)E(14)Y(15)-OMTKY3 and T(13)E(14)Y(15)G(18)M(21)P(32)V(36)-OMTKY3, and for SGPB, S(13)D(14)Y(15)-OMTKY3 and S(13)D(14)Y(15)G(18)I(19)K(21)-OMTKY3. The free energies of association (ΔG(0)) of expressed variants have been measured with the proteases for which they were designed as well as with five other serine proteases and the results are discussed.

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.
