Structural modulation of calmodulin and calmodulin-dependent protein kinase II by pea protein hydrolysates
Bibliographic record
Abstract
The effects of two fractions of pea protein hydrolysate with high levels of positively charged amino acids on the structural conformations of calmodulin (CaM) and CaM-dependent protein kinase II (CaMKII) were determined using fluorescence and circular dichroism methods. In the presence of Ca2 + , addition of the protein hydrolysates to CaM and CaM/CaMKII complex led to increased exposure of aromatic groups as measured by intrinsic and extrinsic fluorescence spectroscopy. Near-UV circular dichroism data revealed an increase in the tertiary structure of CaM in the presence of pea protein hydrolysates. Effect of the protein hydrolysates on the CaM structure was greater with the fraction that contained higher contents of arginine and lysine when compared with the fraction with lower levels of these two amino acids. We concluded that the presence of the pea protein hydrolysates led to rearrangement of the native protein structure and exposure of buried hydrophobic groups of CaM and/or CaMKII.

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.
