Functional Parameters

ΔG of –8.8 Kcal/mol and IC50 of 0.9 ± 0.1

Dry Lab Characterization

Modeling

This peptide was modeled using different software and the top model from Alphafold2 got score 5 out of 6 in our Quality assessment code.

(cbeta_deviations = 0, clashscore = 69.77, molprobity = 4.26, ramachandran_favored = 40, ramachandran_outliers = 60, Qmean_4 = -6.45183, Qmean6 = -5.51397)
