Comparison of the recombinant and authentic forms of the Pasteurella haemolytica A1 glycoprotease
Bibliographic record
Abstract
The O-sialoglycoprotein endopeptidase (glycoprotease, Gcp) is secreted by Pasteurella haemolytica A1, a Gram-negative pathogen associated with bovine pneumonic pasteurellosis. When the cloned gcp gene is expressed in Escherichia coli, the recombinant glycoprotease (rGcp) is exported to the periplasm but does not exhibit enzymatic activity. Polyclonal calf sera and murine monoclonal antibodies to rGcp were used for the further immunological and biochemical characterization of the authentic and recombinant Gcp. The results showed that the gcp gene product is the sole component of Gcp activity. Homologues to the P. haemolytica A1 Gcp were detected by Western immunoblot analysis in a number of Gram-negative bacteria, including E. coli. However, the secretion of Gcp with O-sialoglycoprotein endopeptidase activity appears to be restricted to P. haemolytica A serotypes.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
