Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Glutathione transferases (GSTs) obtained from University of Waterloo, Canada, were purified from Pseudomonas sp. UW4, by glutathione-affinity chromatography, identified through bioinformatic analysis and their substrate specificities were investigated. SDS-polyacrylamide gel electrophoresis revealed that the GST purified using Sulfobromophthalein-glutahione (BSP) affinity column resolved into a single band with low molecular weight (MW) of 17 kDa. Isoselectrofocusing showed it exists in single band with pI value of 6.1. Purified GST was reactive towards ethacrynic acid, 1-chloro-2,4-dinitrobenzene, cumene hydroxide and hydrogen peroxide, but no detectable activity with trans-2-octenal, hepta-2,4-dienal and trans-4-phenyl-3-butene-2-one. This demonstrated that putative GST possessed peroxidase activity but is not involved in lipid peroxidation. The purified GST suggested to be similar to PputUW4_00801 (putative glutathione S-transferase) of Pseudomonas sp. UW4.

Full frame distilled prediction

Teacher imitation

Not 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.
