WebProteolytic cleavage is basically the process of breaking the peptide bonds between amino acids in proteins. This process is carried out by enzymes called peptidases, proteases or proteolytic cleavage enzymes. Proteins often undergo proteolytic processing by specific proteolytic enzymes (proteases/peptidases) before final maturation WebThis specificity allows for the controlled cleavage of proteins when the preference sequence is inserted into flexible loops. It also makes it relatively non-toxic in vivo as the recognized sequence scarcely occurs in proteins. [13]
