How are the enzymes, trypsin, elastase, and chymotrypsin similar?

Homework Answers

Answer #1

Trypsin, Elastase and Chymotrypsinare all these three are digestive enzymes called serine proteases. They digest the proteins by cleaving their peptide bond. In all these enzyme SERINE act as the nucleophilic amino acid at their active site. In this way they are similar.

They are specific for specific molecules. Chymotrypsin cleaves peptide bonds after aromatic or bulky hydrophobic side chains; trypsin requires basic amino acid residues; and elastase cleaves bonds following small uncharged side chains.

Proteolytic enzymes such as trypsin and chymotrypsin are produced by the pancreas. These proteases are very efficient at digesting protein and will even digest tissues. However, there is a mechanism, which activates these enzymes and prevents them from digesting the tissues. What are the mechanisms by which these proteases are activated?

1. Draw the structure of the dipeptide. Gln―Ile 2. What properties are shared by chymotrypsin, trypsin, and elastase? Select all that apply. They all cleave peptide bonds on hydrophobic amino acids. They are all proteases. They all cleave on the carbonyl side of the amino acid. They all cleave peptide bonds on basic amino acids. They have similar three-dimensional structures. They all cleave peptide bonds on hydrophilic amino acids.

A major difficulty in studying the properties of pancreatic serine proteases is that these enzymes are self-digesting. Provide a detailed rationale for the observation that the problem is less severe for solutions of chymotrypsin than it is for solutions of trypsin.
