The precise identification of the scissile peptide bond is paramount in enzymology. For instance, in the context of inhibitors, "The scissile peptide bond of the intact inhibitor in A is identified by an arrow," indicating a specific point of enzymatic attack. The enzyme, a protease, cleaves the peptide bond, which is the scissile bond, between specific amino acid residues, often designated as P1 and P1′ according to the Schechter and Berger nomenclature.Scissile Bond - an overview The residues flanking this bond play a significant role in the enzyme's recognition and cleavage activityThe invention provides novel methodology for the rapid determination of protease cleavage site motifs using a mixture-based orientedpeptidelibrary approach..

Furthermore, structural studies have illuminated how strain within a protein can contribute to the cleavage of a scissile peptide bond. For example, "Structural constraints are found at the autocleavage site, and could thus provide a driving force for autocleavage at the scissile peptide bond." This suggests that the inherent physical forces within a protein can predispose certain peptide bonds to cleavage.A protease cleaves a peptide bond, called the scissile bond, between two amino acid residues named P1 and P1′ (Schechter and Berger, 1967). Residues on the ...
