The role of detergent in refolding of GdnHCl-denatured arginine kinase from shrimp <i>Fenneropenaeus Chinensis</i>: the solubilization of aggregate and refolding in detergent solutions
Bibliographic record
Abstract
Strong aggregation occurred in the refolding route of arginine kinase (AK) denatured with 3 mol GdnHCl/L (GdnHCl, guanidine hydrochloride). The activity recovery of GdnHCl-denatured AK was very low and dependent on the protein concentration in the process of refolding. For denatured AK at 1.2 micromol/L concentration, the recovered activity yield was about 45.2% of the native enzyme, whereas at 5.2 micromol/L the activity recovery yield was only 20% of native activity. The nonionic detergent Triton X-100 and Tween 20 (< or = 100 mmol/L concentration) not only effectively blocked the aggregation but also enabled the denatured AK to recover most of its native activity. The kinetics of aggregate solubilization showed that there was an induction phase dependent on the detergent, but there was no dependency when detergent was absent. The apparent activity recovery had a cooperative relation with detergents in the process of refolding, which suggested the existence of some interaction between the detergent and the refolding intermediate. On the basis of the study results, a scheme of refolding was proposed.

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.
