And so nothing will be cleaved on this side by elastase and so we see that two Vallene residues found in the S One pocket of Elastase block off the majority of the pocket in Elastase. And this allows Elastase to only cleave small hydrophobic residues. And so we see that the majority of the seagram protease is found inside our body. For instance, chimetrypsin trypsin as well as Elastase. Although they use the same catalytic triad to basically catalyze the cleavage of the peptide bonds, they actually differ in the types of amino acids that they cleave. Types of peptide bonds that they cleave.
