PPACKII (trifluoroacetate salt) is a peptidyl electrophile blending aromatic, hydrophobic, and charged residues with a reactive functional group. Researchers apply it to study catalytic sites, covalent interactions, and conformational constraints. Its structural complexity supports advanced mechanistic and kinetic analyses. The TFA salt enhances solubility.
