Kinetics and Molecular Docking Studies of the Inhibitions of Angiotensin Converting Enzyme and Renin Activities by Hemp Seed (<i>Cannabis sativa</i> L.) Peptides
Bibliographic record
Abstract
Four novel peptide sequences (WVYY, WYT, SVYT, and IPAGV) identified from an enzymatic digest of hemp seed proteins were used for enzyme inhibition kinetics and molecular docking studies. Results showed that WVYY (IC50 = 0.027 mM) was a more potent (p < 0.05) ACE-inhibitory peptide than WYT (IC50 = 0.574 mM). However, WYT (IC50 = 0.054 mM) and SVYT (IC50 = 0.063 mM) had similar renin-inhibitory activity, which was significantly better than that of IPAGV (IC50 = 0.093 mM). Kinetics studies showed that WVYY had a lower inhibition constant (Ki) of 0.06 mM and hence greater affinity for ACE when compared to the 1.83 mM obtained for WYT. SVYT had lowest Ki value of 0.89 mM against renin, when compared to the values obtained for WYT and IPAGV. Molecular docking results showed that the higher inhibitory activities of WVYY and SVYT were due to the greater degree of noncovalent bond-based interactions with the enzyme protein, especially formation of higher numbers of hydrogen bonds with active site residues.

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.
